    In this paper, we report findings from a recent survey of international migration from China's Fujian province to the United States. We take advantage of the ethnosurvey approach as used in the Mexican Migration Project. Surveys were done in migrant-sending communities in China as well as in destination communities of New York City. We derive hypotheses from two strands of recent studies-the international migration literature and the market transition debate. Our results are in general consistent with hypotheses derived from cumulative causation of migration. However, because of the geographical location of China as compared to Mexico, there are some differences between the two countries in terms of particular migration patterns to the United States. As expected, at the community level, migration prevalence ratio (measuring migration networks) increases the propensity of migration for other members in the community. In contrast, having a household member migrated previously does not increase the propensity of migration of other household members until debt for previous migration is paid off. Our research clearly demonstrates the value of bringing the case of China into the comparative study of international migration. With respect to market transition theory, we find that political power continues to be an important factor in the order of social stratification in the coastal Fujian province. PMID:19569396

  5. Traders' behavioral coupling and market phase transition

    2017-11-01

    Traditional economic theory is based on the assumption that traders are completely independent and rational; however, trading behavior in the real market is often coupled by various factors. This paper discusses behavioral coupling based on the stock index in the stock market, focusing on the convergence of traders' behavior, its effect on the correlation of stock returns and market volatility. We find that the behavioral consensus in the stock market, the correlation degree of stock returns, and the market volatility all exhibit significant phase transitions with stronger coupling.

  8. Do labour market status transitions predict changes in psychological well-being?

    PubMed

    Flint, Ellen; Bartley, Mel; Shelton, Nicola; Sacker, Amanda

    2013-09-01

    The objective of this study was to establish the direction of causality in the relationship between labour market status and psychological well-being by investigating how transitions between secure employment, insecure employment, unemployment, permanent sickness and other economic inactivity predict changes in psychological well-being over a 16-year period. This study used data from the British Household Panel Survey (1991-2007). Psychological well-being was measured using the 12-item General Health Questionnaire (GHQ-12). Fixed effects models were utilised to investigate how transitions between labour market statuses predicted GHQ-12 score, adjusting for current labour market status and a range of covariates. After taking account of the contemporaneous effects of joblessness on psychological well-being, and the impact of a range of confounding factors, experiencing a transition from employment to joblessness was significantly predictive of poorer psychological well-being. Transitions into employment were not found to have equal and opposite effects: the positive effects of moving into work from unemployment were not as large as the negative effects of job loss. Transitions between secure and insecure employment did not independently predict changes in psychological well-being. A causal relationship between labour market status and psychological well-being is indicated.

    2018-02-14

    The present paper provides first empirical evidence on the relationship between market size and the number of firms in the healthcare industry for a transition economy. We estimate market-size thresholds required to support different numbers of suppliers (firms) for three occupations in the healthcare industry in a large number of distinct geographic markets in Slovakia, taking into account the spatial interaction between local markets. The empirical analysis is carried out for three time periods (1995, 2001 and 2010) which characterise different stages of the transition process. Our results suggest that the relationship between market size and the number of firms differs both across industries and across periods. In particular, we find that pharmacies, as the only completely liberalised market in our dataset, experience the largest change in competitive behaviour during the transition process. Furthermore, we find evidence for correlation in entry decisions across administrative borders, suggesting that future market analysis should aim to capture these regional effects.

  12. Causation in epidemiology

    PubMed Central

    Parascandola, M; Weed, D

    2001-01-01

    Causation is an essential concept in epidemiology, yet there is no single, clearly articulated definition for the discipline. From a systematic review of the literature, five categories can be delineated: production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic. Strengths and weaknesses of these categories are examined in terms of proposed characteristics of a useful scientific definition of causation: it must be specific enough to distinguish causation from mere correlation, but not so narrow as to eliminate apparent causal phenomena from consideration. Two categories—production and counterfactual—are present in any definition of causation but are not themselves sufficient as definitions. The necessary and sufficient cause definition assumes that all causes are deterministic. The sufficient-component cause definition attempts to explain probabilistic phenomena via unknown component causes. Thus, on both of these views, heavy smoking can be cited as a cause of lung cancer only when the existence of unknown deterministic variables is assumed. The probabilistic definition, however, avoids these assumptions and appears to best fit the characteristics of a useful definition of causation. It is also concluded that the probabilistic definition is consistent with scientific and public health goals of epidemiology. In debates in the literature over these goals, proponents of epidemiology as pure science tend to favour a narrower deterministic notion of causation models while proponents of epidemiology as public health tend to favour a probabilistic view. The authors argue that a single definition of causation for the discipline should be and is consistent with both of these aims. It is concluded that a counterfactually-based probabilistic definition is more amenable to the quantitative tools of epidemiology, is consistent with both deterministic and probabilistic phenomena, and serves equally well for the acquisition and the

  13. The limits to cumulative causation: international migration from Mexican urban areas.

    PubMed

    Fussell, Elizabeth; Massey, Douglas S

    2004-02-01

    We present theoretical arguments and empirical research to suggest that the principal mechanisms of cumulative causation do not function in large urban settings. Using data from the Mexican Migration Project, we found evidence of cumulative causation in small cities, rural towns and villages, but not in large urban areas. With event-history models, we found little positive effect of community-level social capital and a strong deterrent effect of urban labor markets on the likelihood of first and later U.S. trips for residents of urban areas in Mexico, suggesting that the social process of migration from urban areas is distinct from that in the more widely studied rural migrant-sending communities of Mexico.

  14. Factual causation in medical negligence.

    PubMed

    Manning, Joanna

    2007-12-01

    The conventional approach to causation in negligence is the "but for" test, decided on the balance of probabilities. Even when supplemented by the "material contribution" principle, satisfying the onus of proof of causation can be an insuperable obstacle for plaintiffs, particularly in medical cases. Yet, having found a breach of duty, a court's sympathies may gravitate toward the plaintiff at this point in the case. Accordingly, courts have sometimes accepted a relaxation of strict causation principles. The judicial devices are described: a special principle of causation in particular duties of care; a shifting burden of proof; "bridging the evidentiary gap" by drawing a robust inference of causation; treating a material increase in risk as sufficient proof of causation; and permitting causation to be established on the basis of the loss of a material chance of achieving a better outcome and discounting damages. In Accident Compensation Corp v Ambros [2007] NZCA 304 the New Zealand Court of Appeal recognised the need for a legal device to ameliorate the injustice sometimes caused by the strict rules of causation, and preferred the "inferential reasoning" approach favoured by the Canadian common law for use in the context of the accident compensation scheme. It is hoped that the New Zealand Supreme Court approves Ambros if the opportunity arises.

  16. Partial information, market efficiency, and anomalous continuous phase transition

    NASA Astrophysics Data System (ADS)

    Yang, Guang; Zheng, Wenzhi; Huang, Jiping

    2014-04-01

    It is a common belief in economics and social science that if there is more information available for agents to gather in a human system, the system can become more efficient. The belief can be easily understood according to the well-known efficient market hypothesis. In this work, we attempt to challenge this belief by investigating a complex adaptive system, which is modeled by a market-directed resource-allocation game with a directed random network. We conduct a series of controlled human experiments in the laboratory to show the reliability of the model design. As a result, we find that even under a small information concentration, the system can still almost reach the optimal (balanced) state. Furthermore, the ensemble average of the system’s fluctuation level goes through a continuous phase transition. This behavior means that in the second phase if too much information is shared among agents, the system’s stability will be harmed instead, which differs from the belief mentioned above. Also, at the transition point, the ensemble fluctuations of the fluctuation level remain at a low value. This phenomenon is in contrast to the textbook knowledge about continuous phase transitions in traditional physical systems, namely, fluctuations will rise abnormally around a transition point since the correlation length becomes infinite. Thus, this work is of potential value to a variety of fields, such as physics, economics, complexity science, and artificial intelligence.

  17. Higher-order phase transitions on financial markets

    NASA Astrophysics Data System (ADS)

    Kasprzak, A.; Kutner, R.; Perelló, J.; Masoliver, J.

    2010-08-01

    Statistical and thermodynamic properties of the anomalous multifractal structure of random interevent (or intertransaction) times were thoroughly studied by using the extended continuous-time random walk (CTRW) formalism of Montroll, Weiss, Scher, and Lax. Although this formalism is quite general (and can be applied to any interhuman communication with nontrivial priority), we consider it in the context of a financial market where heterogeneous agent activities can occur within a wide spectrum of time scales. As the main general consequence, we found (by additionally using the Saddle-Point Approximation) the scaling or power-dependent form of the partition function, Z(q'). It diverges for any negative scaling powers q' (which justifies the name anomalous) while for positive ones it shows the scaling with the general exponent τ(q'). This exponent is the nonanalytic (singular) or noninteger power of q', which is one of the pilar of higher-order phase transitions. In definition of the partition function we used the pausing-time distribution (PTD) as the central one, which takes the form of convolution (or superstatistics used, e.g. for describing turbulence as well as the financial market). Its integral kernel is given by the stretched exponential distribution (often used in disordered systems). This kernel extends both the exponential distribution assumed in the original version of the CTRW formalism (for description of the transient photocurrent measured in amorphous glassy material) as well as the Gaussian one sometimes used in this context (e.g. for diffusion of hydrogen in amorphous metals or for aging effects in glasses). Our most important finding is the third- and higher-order phase transitions, which can be roughly interpreted as transitions between the phase where high frequency trading is most visible and the phase defined by low frequency trading. The specific order of the phase transition directly depends upon the shape exponent α defining the stretched

  18. Top-down causation and social structures

    PubMed Central

    Elder-Vass, Dave

    2012-01-01

    Top-down causation has been implicit in many sociological accounts of social structure and its influence on social events, but the social sciences have struggled to provide a coherent account of top-down causation itself. This paper summarizes a critical realist view of causation and emergence, shows how it supports a plausible account of top-down causation and then applies this account to the social world. The argument is illustrated by an examination of the concept of a norm circle, a kind of social entity that, it is argued, is causally responsible for the influence of normative social institutions. Nevertheless, social entities are structured rather differently from ordinary material ones, with the result that the compositional level structure of reality implicit in the concept of top-down causation has some limitations in the social world. The paper closes by considering what might be involved in examining how top-down causation can be shown to be at work in the social domain. PMID:23386963

    Research into nursing home transitions has given limited attention to the facility or community contexts. To identify facility and market factors affecting transitions of nursing home residents back to the community. Multilevel models were used to estimate effects of facility and market factors on facility-level community discharge rates after controlling for resident demographic, health, and functional conditions. Facility discharge rates were adjusted using Empirical Bayes estimation. Annual cohort of first-time admissions (N=24,648) to 378 Minnesota nursing facilities in 75 nursing home markets from July 2005 to June 2006. Community discharge within 90 days of admission; facility occupancy, payer mix, ownership, case-mix acuity, size, admissions from hospitals, nurse staffing level, and proportion of admissions preferring or having support to return to the community; and nursing market population size, average occupancy, market concentration, and availability of home and community-based services. Rates of community discharge (Empirical Bayes residual) were highest in facilities with more residents preferring community discharge, more Medicare days, higher nurse staffing levels, and higher occupancy. In addition, facilities had higher community discharge rates if they were located in markets with a greater ratio of home and community-based services recipients to nursing home residents and with larger populations. State Medicaid programs should undertake system-level interventions that encourage nursing facilities to reduce unused bed capacity, balance the mix of payers, invest in nurse staffing, and take other steps to promote community discharges. In addition, states should increase home and community-based services, particularly in markets with low community discharge rates.

    2015-06-01

    South-eastern European socioeconomic transition followed by extensive health systems reforms has completely changed the pharmaceuticals market landscape in the region. Serbia, as the largest Western Balkans market, may serve as an example of such changes. Descriptive trend analysis of national-level dispensing of medicines in Serbia 2004-2012 was performed. Total public health expenditure in Serbia increased sharply in less than a decade (€1,175,158,679 to €1,847,971,776); public spending on pharmaceuticals doubled (€339,279,304 to €742,013,976). Market growth was primarily driven by statins, novel platelet aggregation inhibitors, monoclonal antibodies and combined preparations indicated in asthma and chronic obstructive pulmonary disease. The pharmaceutical market of Serbia has undergone thorough and complete transformation from within. Serious crisis of medicine supply sustainability is currently shaking Balkan health systems due to increasing public debt worsened by global recession. More responsible reimbursement policy rooted in cost-effectiveness principle is needed in years to come.

    A preliminary investigation into different eating patterns among Thai consumers who shop at fresh markets as opposed to supermarkets in Chiang Mai. A short questionnaire adopted from a previous study was administered to the forty-four participants, who comprised supermarket users, fresh market users and people who consistently shopped at both supermarkets and fresh markets. Participants were recruited within four fresh markets and two food courts attached to supermarkets in Chiang Mai. Chiang Mai residents who agreed to participate in the study. Equal numbers were regular fresh market and supermarket users. Initial results suggest an association between shopping at supermarkets and attributing bread with culinary value. Supermarkets may be potentially significant players in the 'nutrition transition', providing Thais more convenient shopping at some cost to their healthy food choices.

  7. On Reciprocal Causation in the Evolutionary Process.

    PubMed

    Svensson, Erik I

    2018-01-01

    Recent calls for a revision of standard evolutionary theory (SET) are based partly on arguments about the reciprocal causation. Reciprocal causation means that cause-effect relationships are bi-directional, as a cause could later become an effect and vice versa. Such dynamic cause-effect relationships raise questions about the distinction between proximate and ultimate causes, as originally formulated by Ernst Mayr. They have also motivated some biologists and philosophers to argue for an Extended Evolutionary Synthesis (EES). The EES will supposedly expand the scope of the Modern Synthesis (MS) and SET, which has been characterized as gene-centred, relying primarily on natural selection and largely neglecting reciprocal causation. Here, I critically examine these claims, with a special focus on the last conjecture. I conclude that reciprocal causation has long been recognized as important by naturalists, ecologists and evolutionary biologists working in the in the MS tradition, although it it could be explored even further. Numerous empirical examples of reciprocal causation in the form of positive and negative feedback are now well known from both natural and laboratory systems. Reciprocal causation have also been explicitly incorporated in mathematical models of coevolutionary arms races, frequency-dependent selection, eco-evolutionary dynamics and sexual selection. Such dynamic feedback were already recognized by Richard Levins and Richard Lewontin in their bok The Dialectical Biologist . Reciprocal causation and dynamic feedback might also be one of the few contributions of dialectical thinking and Marxist philosophy in evolutionary theory. I discuss some promising empirical and analytical tools to study reciprocal causation and the implications for the EES. Finally, I briefly discuss how quantitative genetics can be adapated to studies of reciprocal causation, constructive inheritance and phenotypic plasticity and suggest that the flexibility of this approach

    2015-01-01

    People affected by substance use disorders often experience sub-optimal employment outcomes. The role of drug use in processes that produce and entrench labour market precarity among people who inject drugs (PWID) have not, however, been fully described. We recruited 22 PWID from ongoing prospective cohort studies in Vancouver, Canada and conducted semi-structured retrospective interviews and employed a thematic analysis that draws on concepts from life course theory to explore mechanisms and pathways linking drug use and labour market trajectories. Narratives identified processes corresponding to: causation, whereby suboptimal employment outcomes led to harmful drug use; direct selection, where impairment, health complications or drug seeking activities selected individuals out of employment; and indirect selection, where external factors, such as catastrophic events, marked the initiation or intensification of substance use concurrent with sudden changes in capacities for employment. Catastrophic events linking negative transitions in both drug use and labour market trajectories were of primary importance, demarcating critical initiation and transitional events in individual risk trajectories. These results challenge conventional assumptions about the primacy of drug use in determining employment outcomes among PWID, and suggest the importance of multi-dimensional supports to mitigate the initiation, accumulation and entrenchment of labour market and drug-related disadvantage.

  10. Socio-technical transition as a co-evolutionary process: Innovation and the role of niche markets in the transition to motor vehicles

    NASA Astrophysics Data System (ADS)

    Birky, Alicia K.

    2008-10-01

    Significant reductions in greenhouse emissions from personal transportation will require a transition to an alternative technology regime based on renewable energy sources. Two bodies of research, the quasi-evolutionary (QE) model and the multi-level perspective (MLP) assert that processes within niches play a fundamental role in such transitions. This research asks whether the description of transitions based on this niche hypothesis and its underlying assumptions is consistent with the historical U.S. transition to motor vehicles at the beginning of the 20th century. Unique to this dissertation is the combination of the perspective of the entrepreneur with co-evolutionary approaches to socio-technical transitions. This approach is augmented with concepts from the industry life-cycle model and with a taxonomy of mechanisms of learning. Using this analytic framework, I examine specifically the role of entrepreneurial behavior and processes within and among firms in the co-evolution of technologies and institutions during the transition to motor vehicles. I find that niche markets played an important role in the development of the technology, institutions, and the industry. However, I also find that the diffusion of the automobile is not consistent with the niche hypothesis in the following ways: (1) product improvements and cost reductions were not realized in niche markets, but were achieved simultaneously with diffusion into mass markets; (2) in addition to learning-by-doing and learning-by-interacting with users, knowledge spillovers and interacting with suppliers were critical in this process; (3) cost reductions were not automatic results of expanding markets, but rather arose from the strategies of entrepreneurs based on personal perspectives and values. This finding supports the use of a behavioral approach with a micro-focus in the analysis of socio-technical change. I also find that the emergence and diffusion of the motor vehicle can only be understood by

  13. A study on the mutual causation of suicide reporting and suicide incidences.

    PubMed

    Yip, Paul S F; Kwok, Simon Sai Man; Chen, Feng; Xu, Xiaochen; Chen, Ying-Yeh

    2013-05-15

    Little research has been done on the complex relationships between the effect of news reporting on suicide incidence and vice versa (i.e., mutual causation). Furthermore, few studies have examined whether the entry of a new media outlet into a market changes the media dynamics in that market. A recursive two-way feedback model was used to test for mutual causation between suicide reporting and suicide incidence on a daily basis. We applied the model to examine the effect of the arrival of the Apple Daily (AD) newspaper in Taiwan and whether its suicide reporting affected the suicide incidence and suicide reporting of two other newspapers, the United Daily (UD) and the China Times (CT). The AD's entry into Taiwan led to a major shift in the relationship between suicide incidence and suicide reporting. The AD stimulated more suicide coverage by the UD and the CT the following day; conversely, the UD and the CT had no such impact on the AD. Before the entry of the AD, there was little correlation between daily suicide incidence and suicide reporting, but the suicide reporting of the UD and CT correlated significantly with daily suicide incidence after the entry of the AD. Media impact was assessed by number of news items; detailed content analysis of the reporting was not conducted. The vicious business competition facing new dailies in Taiwan's media market has changed the mass media ecology. Efforts to prevent suicide by regulating the media should closely monitor not only the behavior of newcomers, but also the established news media's reaction to new competitors.

  15. FORUM: Dynamics and Causation of Environmental Equity, Locally Unwanted Land Uses, and Neighborhood Changes

    PubMed

    1997-09-01

    / Why are some environmental risks distributed disproportionately in the neighborhoods of the minorities and the poor? A hypothesis was proposed in a recent study that market dynamics contributed to the current environmental inequity. That is, locally unwanted land uses (LULUs) make the host communities home to more poor people and people of color. This hypothesis was allegedly supported by a Houston case study, whereby its author analyzed the postsiting changes of the socioeconomic characteristics of the neighborhoods surrounding solid waste facilities. I argue that such an analysis of postsiting changes alone is insufficient to test the causation hypothesis. Instead, I propose a conceptual framework for analysis of environmental equity dynamics and causation. I suggest that the presiting neighborhood dynamics and the characteristics of control neighborhoods be analyzed as the first test for the causation hypothesis. Furthermore, I present theories of neighborhood change and then examine alternative hypotheses that these theories offer for explaining neighborhood changes and for the roles of LULUs in neighborhood changes. These alternative hypotheses should be examined when analyzing the relationship between LULUs and neighborhood changes in a metropolitan area. Using this framework of analysis, I revisited the Houston case. First, I found no evidence that provided support for the hypothesis that the presence of LULUs made the neighborhoods home to more blacks and poor people, contrary to the conclusion made by the previous study. Second, I examined alternative hypotheses for explaining neighborhood changes-invasion-succession, other push forces, and neighborhood life-cycle; the former two might offer better explanation.KEY WORDS: Environmental equity and justice; Locally unwanted lane uses; Siting; Market dynamics; Invasion-succession; Neighborhood changes

    We show that the log-periodic power law singularity model (LPPLS), a mathematical embodiment of positive feedbacks between agents and of their hierarchical dynamical organization, has a significant predictive power in financial markets. We find that LPPLS-based strategies significantly outperform the randomized ones and that they are robust with respect to a large selection of assets and time periods. The dynamics of prices thus markedly deviate from randomness in certain pockets of predictability that can be associated with bubble market regimes. Our hybrid approach, marrying finance with the trading strategies, and critical phenomena with LPPLS, demonstrates that targeting information related to phase transitions enables the forecast of financial bubbles and crashes punctuating the dynamics of prices.

  19. Pathways linking drug use and labour market trajectories: the role of catastrophic events.

    2016-01-01

    People affected by substance use disorders often experience sub-optimal employment outcomes. The role of drug use in processes that produce and entrench labour market precarity among people who inject drugs (PWID) have not, however, been fully described. We recruited 22 PWID from ongoing prospective cohort studies in Vancouver, Canada, with whom we conducted semi-structured retrospective interviews and then employed a thematic analysis that drew on concepts from life course theory to explore the mechanisms and pathways linking drug use and labour market trajectories. The participants' narratives identified processes corresponding to causation, whereby suboptimal employment outcomes led to harmful drug use; direct selection, where impairment, health complications or drug-seeking activities selected individuals out of employment; and indirect selection, where external factors, such as catastrophic events, marked the initiation or intensification of substance use concurrent with sudden changes in capacities for employment. Catastrophic events linking negative transitions in both drug use and labour market trajectories were of primary importance, demarcating critical initiation and transitional events in individual risk trajectories. These results challenge conventional assumptions about the primacy of drug use in determining employment outcomes among PWID and suggest the importance of multidimensional support to mitigate the initiation, accumulation and entrenchment of labour market and drug-related disadvantage. © 2015 Foundation for the Sociology of Health & Illness.

  20. Top-down causation and emergence: some comments on mechanisms

    PubMed Central

    Ellis, George F. R.

    2012-01-01

    Both bottom-up and top-down causation occur in the hierarchy of structure and causation. A key feature is multiple realizability of higher level functions, and consequent existence of equivalence classes of lower level variables that correspond to the same higher level state. Five essentially different classes of top-down influence can be identified, and their existence demonstrated by many real-world examples. They are: algorithmic top-down causation; top-down causation via non-adaptive information control, top-down causation via adaptive selection, top-down causation via adaptive information control and intelligent top-down causation (the effect of the human mind on the physical world). Through the mind, abstract entities such as mathematical structures have causal power. The causal slack enabling top-down action to take place lies in the structuring of the system so as to attain higher level functions; in the way the nature of lower level elements is changed by context, and in micro-indeterminism combined with adaptive selection. Understanding top-down causation can have important effects on society. Two cases will be mentioned: medical/healthcare issues, and education—in particular, teaching reading and writing. In both cases, an ongoing battle between bottom-up and top-down approaches has important consequences for society. PMID:23386967

  2. Coarse-graining as a downward causation mechanism

    Flack, Jessica C.

    2017-11-01

    Downward causation is the controversial idea that `higher' levels of organization can causally influence behaviour at `lower' levels of organization. Here I propose that we can gain traction on downward causation by being operational and examining how adaptive systems identify regularities in evolutionary or learning time and use these regularities to guide behaviour. I suggest that in many adaptive systems components collectively compute their macroscopic worlds through coarse-graining. I further suggest we move from simple feedback to downward causation when components tune behaviour in response to estimates of collectively computed macroscopic properties. I introduce a weak and strong notion of downward causation and discuss the role the strong form plays in the origins of new organizational levels. I illustrate these points with examples from the study of biological and social systems and deep neural networks. This article is part of the themed issue 'Reconceptualizing the origins of life'.

  3. Historical Perspectives of the Causation of Lung Cancer

    PubMed Central

    2015-01-01

    Lung cancer is the leading cause of cancer deaths worldwide. Less-known forces are involved in the etiology of lung cancer and have relevant implications for providers in ameliorating care. The purpose of this article is to discuss theories of causation of lung cancer using historical analyses of the evolution of the disease and incorporating related explanations integrating the relationships of science, nursing, medicine, and society. Literature from 160 years was searched and Thagard’s model of causation networks was used to exhibit how nursing and medicine were significant influences in lung cancer causation theory. Disease causation interfaces with sociological norms of behavior to form habits and rates of health behavior. Historically, nursing was detrimentally manipulated by the tobacco industry, engaging in harmful smoking behaviors, thus negatively affecting patient care. Understanding the underlying history behind lung cancer causation may empower nurses to play an active role in a patient’s health. PMID:28462309

  5. Labor market outcomes and the transition to adulthood.

    PubMed

    Danziger, Sheldon; Ratner, David

    2010-01-01

    According to Sheldon Danziger and David Ratner, changes in the labor market over the past thirty-five years, such as labor-saving technological changes, increased globalization, declining unionization, and the failure of the minimum wage to keep up with inflation, have made it more difficult for young adults to attain the economic stability and self-sufficiency that are important markers of the transition to adulthood. Young men with no more than a high school degree have difficulty earning enough to support a family. Even though young women have achieved gains in earnings, employment, and schooling relative to men in recent decades, those without a college degree also struggle to achieve economic stability and self-sufficiency. The authors begin by describing trends in labor market outcomes for young adults-median annual earnings, the extent of low-wage work, employment rates, job instability, and the returns to education. Then they examine how these outcomes may contribute to delays in other markers of the transition to adulthood-completing an education, establishing independent living arrangements, and marrying and having children. They conclude that adverse changes in labor market outcomes are related to those delays but have not been shown to be the primary cause. Danziger and Ratner next consider several public policy reforms that might improve the economic outlook for young adults. They recommend policies that would increase the returns to work, especially for less-educated workers. They propose raising the federal minimum wage and adjusting it annually to maintain its value relative to the median wage. Expanding the Earned Income Tax Credit for childless low-wage workers, the authors say, could also raise the take-home pay of many young adult workers, with minimal adverse employment effects. New policies should also provide work opportunities for young adults who cannot find steady employment either because of poor economic conditions or because of physical

  10. A computable expression of closure to efficient causation.

    PubMed

    Mossio, Matteo; Longo, Giuseppe; Stewart, John

    2009-04-07

    In this paper, we propose a mathematical expression of closure to efficient causation in terms of lambda-calculus; we argue that this opens up the perspective of developing principled computer simulations of systems closed to efficient causation in an appropriate programming language. An important implication of our formulation is that, by exhibiting an expression in lambda-calculus, which is a paradigmatic formalism for computability and programming, we show that there are no conceptual or principled problems in realizing a computer simulation or model of closure to efficient causation. We conclude with a brief discussion of the question whether closure to efficient causation captures all relevant properties of living systems. We suggest that it might not be the case, and that more complex definitions could indeed create crucial some obstacles to computability.

  11. Hierarchy, causation and explanation: ubiquity, locality and pluralism

    PubMed Central

    Love, Alan C.

    2012-01-01

    The ubiquity of top-down causal explanations within and across the sciences is prima facie evidence for the existence of top-down causation. Much debate has been focused on whether top-down causation is coherent or in conflict with reductionism. Less attention has been given to the question of whether these representations of hierarchical relations pick out a single, common hierarchy. A negative answer to this question undermines a commonplace view that the world is divided into stratified ‘levels’ of organization and suggests that attributions of causal responsibility in different hierarchical representations may not have a meaningful basis for comparison. Representations used in top-down and bottom-up explanations are primarily ‘local’ and tied to distinct domains of science, illustrated here by protein structure and folding. This locality suggests that no single metaphysical account of hierarchy for causal relations to obtain within emerges from the epistemology of scientific explanation. Instead, a pluralist perspective is recommended—many different kinds of top-down causation (explanation) can exist alongside many different kinds of bottom-up causation (explanation). Pluralism makes plausible why different senses of top-down causation can be coherent and not in conflict with reductionism, thereby illustrating a productive interface between philosophical analysis and scientific inquiry.

    The purpose of this study was to explore how the inquiry of cultural diabetes causation beliefs can improve Hispanic/Latino patient self-management. Two semistructured focus groups were conducted with 13 Hispanic/Latinos adults diagnosed with type 2 diabetes mellitus. Prior to taking part in the group discussion, participants completed a demographic survey and the Illness Perception Questionnaire-Revised. The top 5 diabetes causation items endorsed by participants per the questionnaire included stress or worry, behavior, hereditary, diet/eating habits, and family problems/worries. The qualitative analysis revealed stress as a recurring theme for a cause of diabetes. Work stress was specifically identified as a contributor to unhealthy eating and diabetes. Most participants were aware of and believed in susto and referred to it as coraje (anger). Participants believed that asking patients about their diabetes causation beliefs and emotional status can help health professionals (1) better understand the patient and (2) identify and prioritize diabetes treatments. Participants also indicated that the role of doctors is important and the encouragement that they give to patients is clinically and spiritually valued. Stress was identified as a cause of diabetes in addition to unhealthy diets and heredity. Asking patients about diabetes causation beliefs and emotional status may help prioritize treatment and management goals. © 2015 The Author(s).

    Much effort is put into identifying causative quantitative trait nucleotides (QTN) in animal breeding, empowered by the availability of dense single nucleotide polymorphism (SNP) information. Genomic selection using traditional SNP information is easily implemented for any number of genotyped individuals using single-step genomic best linear unbiased predictor (ssGBLUP) with the algorithm for proven and young (APY). Our aim was to investigate whether ssGBLUP is useful for genomic prediction when some or all QTN are known. Simulations included 180,000 animals across 11 generations. Phenotypes were available for all animals in generations 6 to 10. Genotypes for 60,000 SNPs across 10 chromosomes were available for 29,000 individuals. The genetic variance was fully accounted for by 100 or 1000 biallelic QTN. Raw genomic relationship matrices (GRM) were computed from (a) unweighted SNPs, (b) unweighted SNPs and causative QTN, (c) SNPs and causative QTN weighted with results obtained with genome-wide association studies, (d) unweighted SNPs and causative QTN with simulated weights, (e) only unweighted causative QTN, (f-h) as in (b-d) but using only the top 10% causative QTN, and (i) using only causative QTN with simulated weight. Predictions were computed by pedigree-based BLUP (PBLUP) and ssGBLUP. Raw GRM were blended with 1 or 5% of the numerator relationship matrix, or 1% of the identity matrix. Inverses of GRM were obtained directly or with APY. Accuracy of breeding values for 5000 genotyped animals in the last generation with PBLUP was 0.32, and for ssGBLUP it increased to 0.49 with an unweighted GRM, 0.53 after adding unweighted QTN, 0.63 when QTN weights were estimated, and 0.89 when QTN weights were based on true effects known from the simulation. When the GRM was constructed from causative QTN only, accuracy was 0.95 and 0.99 with blending at 5 and 1%, respectively. Accuracies simulating 1000 QTN were generally lower, with a similar trend.

    2012-02-06

    I have two main aims. The first is general, and more philosophical (§2). The second is specific, and more closely related to physics (§§3 and 4). The first aim is to state my general views about laws and causation at different 'levels'. The main task is to understand how the higher levels sustain notions of law and causation that 'ride free' of reductions to the lower level or levels. I endeavour to relate my views to those of other symposiasts. The second aim is to give a framework for describing dynamics at different levels, emphasizing how the various levels' dynamics can mesh or fail to mesh. This framework is essentially that of elementary dynamical systems theory. The main idea will be, for simplicity, to work with just two levels, dubbed 'micro' and 'macro', which are related by coarse-graining. I use this framework to describe, in part, the first four of Ellis' five types of top-down causation.

  18. Transition from Exponential to Power Law Income Distributions in a Chaotic Market

    NASA Astrophysics Data System (ADS)

    Pellicer-Lostao, Carmen; Lopez-Ruiz, Ricardo

    Economy is demanding new models, able to understand and predict the evolution of markets. To this respect, Econophysics offers models of markets as complex systems, that try to comprehend macro-, system-wide states of the economy from the interaction of many agents at micro-level. One of these models is the gas-like model for trading markets. This tries to predict money distributions in closed economies and quite simply, obtains the ones observed in real economies. However, it reveals technical hitches to explain the power law distribution, observed in individuals with high incomes. In this work, nonlinear dynamics is introduced in the gas-like model in an effort to overcomes these flaws. A particular chaotic dynamics is used to break the pairing symmetry of agents (i, j) ⇔ (j, i). The results demonstrate that a "chaotic gas-like model" can reproduce the Exponential and Power law distributions observed in real economies. Moreover, it controls the transition between them. This may give some insight of the micro-level causes that originate unfair distributions of money in a global society. Ultimately, the chaotic model makes obvious the inherent instability of asymmetric scenarios, where sinks of wealth appear and doom the market to extreme inequality.

  20. Time, space and form: Necessary for causation in health, disease and intervention?

    PubMed

    Evans, David W; Lucas, Nicholas; Kerry, Roger

    2016-06-01

    Sir Austin Bradford Hill's 'aspects of causation' represent some of the most influential thoughts on the subject of proximate causation in health and disease. Hill compiled a list of features that, when present and known, indicate an increasing likelihood that exposure to a factor causes-or contributes to the causation of-a disease. The items of Hill's list were not labelled 'criteria', as this would have inferred every item being necessary for causation. Hence, criteria that are necessary for causation in health, disease and intervention processes, whether known, knowable, or not, remain undetermined and deserve exploration. To move beyond this position, this paper aims to explore factors that are necessary in the constitution of causative relationships between health, disease processes, and intervention. To this end, disease is viewed as a causative pathway through the often overlapping stages of aetiology, pathology and patho-physiology. Intervention is viewed as a second, independent causative pathway, capable of causing changes in health for benefit or harm. For the natural course of a disease pathway to change, we argue that intervention must not only occupy the same time and space, but must also share a common form; the point at which the two pathways converge and interact. This improved conceptualisation may be used to facilitate the interpretation of clinical observations and inform future research, particularly enabling predictions of the mechanistic relationship between health, disease and intervention.

    Studies of health effects of urea formaldehyde foam insulation (UFFI) were critically reviewed by means of accepted rules for evidence of causation. Three categories of health effects were examined: reported symptoms, primarily of the upper respiratory tract, lower respiratory tract disease and cancer. Most of the studies purporting to demonstrate health effects of UFFI failed to meet minimal methodologic criteria for evidence of causation. Evidence from the adequate studies provides little support for the hypothesis of a causative role of UFFI in health problems. PMID:3512066

    2011-11-01

    Retro-causation has been experimentally verified by Bem and proposed by Kafatos in the form of space-time non-locality in the quantum framework. Every theory includes, beyond its specific axioms, the principles of logical communication (logical language), through which it is defined. This communication obeys the Aristotelian logic (Classical Logic), the Leibniz Sufficient Reason Principle, and a hidden axiom, which basically states that there is anterior-posterior relationship everywhere in communication. By means of a theorem discussed here, it can be proved that the communication mentioned implies contradictory statements, which can only be transcended through silence, i.e. the absence of any statements. Moreover, the breaking of silence is meaningful through the claim for minimum contradictions, which implies the existence of both a logical and an illogical dimension; contradictions refer to causality, implying its opposite, namely retro-causation, and the anterior posterior axiom, implying space-time non-locality. The purpose of this paper is to outline a framework accounting for retro-causation, through both purely theoretical and reality based points of view.

    Causation is a frustrating subject. Suppose one begins with some promising idea such as that causation is counterfactual dependence or statistical relevance. One then develops this idea with care and intelligence, revises and improves it to cope with criticisms, and by the time one is finished, sane people will be looking elsewhere. If one wants conclusive reasons to reject the counterfactual theory of causation, one can do no better than to read Lewis' (1986) many postscripts. If one wants the best refutation of a probabilistic theory of causation, then one should read my colleague, Ellery Eells' (1991) magisterial defense. In Physical Causation, Phil Dowe performs the same service for physical process/interaction theories of causation.

    Mason, J K

    2004-01-01

    The paper considers the status of the wrongful life action particularly in the light of the recent acceptance of such actions in continental Europe. It is considered that the hurdle of causation is still not adequately overcome in these cases and, in a search for an answer to the difficulty, the author re-examines the Canadian case of Cherry v Borsman. This case was originally thought of as one of wrongful life associated with a negligently performed abortion and the paper attempts to overcome the problems of causation by comparing and contrasting the roles of the genetic counsellor and the abortionist. While the attempt is by no means wholly successful, it also serves to draw attention to some significant differences between wrongful life actions based on physical and mental disability in the neonate.

    This article evaluates abuse-deterrent formulations (ADFs) as a method to reduce prescription drug abuse while ensuring access to vital medications for individuals with legitimate need; assesses the pros and cons of ADFs and the current state of ADF adoption in the market; and develops policy recommendations to transition the market to ADFs. Although abuse-deterrent technology is still in its nascent stages, ADFs have been proven to reduce prescription drug abuse and its consequences, and even an incremental reduction in abuse can have a significant impact on the nation by reducing the costly social, physical, mental, and public health problems resulting from abuse. Federal ADF policy does not reflect the urgency of the prescription drug abuse epidemic and does not go far enough toward changing the status quo. Policies must be implemented to encourage innovation and a market shift toward ADFs by ensuring any generic medication that references a branded ADF demonstrates that it does not have abuse-deterrent properties inferior to the branded ADF product. Policies must also require federal prescription drug benefit plans to cover ADFs to ensure consumers have access to such medications. PMID:25922655

    Establishing an argument of causation is an important research activity with major clinical and scientific implications. Sir Austin Bradford Hill proposed criteria to establish such an argument. These criteria include the strength of the association, consistency, specificity, temporal sequence, biological gradient, biologic rationale, coherence, experimental evidence, and analogous evidence. These criteria are reviewed with the goal of facilitating an increase in rigor for establishing arguments of causation in neuropsychiatry. The challenges and opportunities related to these criteria in neuropsychiatry are reviewed, as are two important arguments for causation: one for poststroke depression and one for brain injury as a cause of psychiatric disorders.

    1994-01-01

    Hospital marketing is an intricate and complex process. Especially difficult is the transition the hospital marketer must make from designing marketing strategies to implementing those strategies. This transition usually causes the marketer to call upon a different set of skills. These skills involve managing the personnel needed to implement the designed marketing strategy. Unfortunately, little in the way of formal training is provided the marketer for developing these management skills. Therefore, the authors have comprised a series of tactical procedures designed to assist the hospital marketer to survive this transition. Using these tactics for decision-making guidelines may help to improve the management of the hospital's marketing effort.

    The essays by Tougas and Willeford address, among other things, a number of ways to understand causation, which play crucial roles in the framework of thinking proposed by Pauli and Jung. The intention of my following reply is to say a few words about how these options are related to one another within our reconstruction of the Pauli-Jung conjecture. In the tradition of the sciences, looking for causation has become a virtually innate reflex to interpret empirically observed correlations. The concept of synchronicity suggests looking for meaningful coincidences as an alternative, complementary interpretation, particularly appropriate for psychophysical correlations. © 2014, The Society of Analytical Psychology.

  17. Age and gender differences in the impact of labour-market transitions on subjective health in Germany.

    PubMed

    Unger, Stefanie; Tisch, Anita; Tophoven, Silke

    2018-02-01

    Applying a gender- and age group-sensitive approach, we investigated the effect of labour-market transitions (job loss and re-employment) on subjective physical and mental health. A combination of the difference-in-differences approach and propensity score matching controls for selectivity and initial health differences. This allowed us to analyse the causal effect of job loss and re-employment on subjective health. We made use of data from the German Panel Study Labour Market and Social Security and combined survey information with administrative records of the Federal Employment Agency for employed and unemployed men and women 31-60 years of age ( n = 2213). We controlled for labour-market experiences before the time period under study and for labour-market transitions between the interviews. Subjective health was assessed using the SF-12 health questionnaire, enabling us to differentiate between subjective mental and physical health functioning. We found that physical health was affected mainly in older persons between 45 and 60 years old. Controlling for covariates using propensity score matching, mental health was affected only when living-wage jobs (i.e. jobs that provide sufficient income to achieve a defined minimum standard of living above the social benefit level) are gained or lost. Younger women showed a significant improvement in mental health after re-employment. In contrast, job loss affected only older individuals' mental health, with a particularly negative effect observed for men. Our results not only showed that women and men are affected differently by job loss and re-employment, but also that age is an important factor. Older men were affected most severely by job loss, whereas re-employment was found to improve mental health only in women aged 31-44 years. It is therefore important to address the health problems of different socio-demographic groups separately, and to apply active labour-market policies with regard to unemployed men and

  20. Caring for medically unexplained physical symptoms after toxic environmental exposures: effects of contested causation.

    PubMed Central

    Engel, Charles C; Adkins, Joyce A; Cowan, David N

    2002-01-01

    Medically unexplained physical symptoms (MUPS) are persistent idiopathic symptoms that drive patients to seek medical care. MUPS syndromes include chronic fatigue syndrome, fibromyalgia syndrome, and multiple chemical sensitivities. When MUPS occur after an environmental exposure or injury, an adversarial social context that we call "contested causation" may ensue. Contested causation may occur publicly and involve media controversy, scientific disagreement, political debate, and legal struggles. This adversarial social context may diminish the effectiveness of the provider-patient relationship. Contested causation also may occur privately, when disagreement over the causes of MUPS takes place in the patient-provider context. These patient-provider disagreements over causation often occur because of the enigmatic nature of MUPS. We suggest that a context of contested causation may have serious negative effects on healthcare for individuals with MUPS. Context plays a larger role in MUPS care than it does for most medical care because of the uncertain nature of MUPS, the reliance of standard MUPS therapies on a potentially tenuous patient-provider partnership, and the clinical need to rely routinely on subjective MUPS assessments that often yield discordant patient and provider conclusions. Contested causation may erode patient-provider trust, test the provider's self-assurance and capacity to share power with the patient, and raise problematic issues of compensation, reparation, and blame. These issues may distract patients and providers from therapeutic goals. In occupational and military settings, the adverse impact of contested causation on the patient-provider partnership may diminish therapeutic effectiveness to a greater degree than it does in other medical settings. Contested causation therefore raises questions regarding generalizability of standard therapies for MUPS and related syndromes to these settings. Future research is needed to learn whether

    2008-03-01

    China and the Former Soviet Union have both undergone substantial political and economic change in recent years as they began the transition from planned to more liberal market economies. The approaches to market liberalization in Russia (privatization in the minimum time) and China (gradual liberalization of prices and slow withdrawal of agricultural subsidies) were quite different. This paper examines some of the health implications associated with these changes, particularly in relation to the increasing burden of diet-related chronic diseases. The changing patterns of tobacco and alcohol use, increase in sedentary lifestyles and increased consumption of non-traditional, energy-dense processed foods, high in salt, fat and sugar are examined, as are the strategies used by foreign direct investors in these emerging markets to ensure market penetration, to gain a fuller understanding of how children and adults' choices of food are being influenced as a result of these socioeconomic changes. Some of the threats and opportunities facing Chinese and foreign food producers in these new conditions are assessed. It is suggested that to ensure successful prevention of future diet-related chronic diseases in such rapidly changing conditions, there needs to be a move beyond reliance solely on health education programmes and individual or local community-based interventions. A series of strategies involving multiple stakeholders should be considered as options for intervention.

    2010-10-01

    The paper makes a case for there being causation in the form of causal properties or causal structures in the domain of fundamental physics. That case is built in the first place on an interpretation of quantum theory in terms of state reductions so that there really are both entangled states and classical properties, GRW being the most elaborate physical proposal for such an interpretation. I then argue that the interpretation that goes back to Everett can also be read in a causal manner, the splitting of the world being conceivable as a causal process. Finally, I mention that the way in which general relativity theory conceives the metrical field opens up the way for a causal conception of the metrical properties as well.

    Must higher level biological processes always be derivable from lower level data and mechanisms, as assumed by the idea that an organism is completely defined by its genome? Or are higher level properties necessarily also causes of lower level behaviour, involving actions and interactions both ways? This article uses modelling of the heart, and its experimental basis, to show that downward causation is necessary and that this form of causation can be represented as the influences of initial and boundary conditions on the solutions of the differential equations used to represent the lower level processes. These insights are then generalized. A priori, there is no privileged level of causation. The relations between this form of 'biological relativity' and forms of relativity in physics are discussed. Biological relativity can be seen as an extension of the relativity principle by avoiding the assumption that there is a privileged scale at which biological functions are determined.

    2015-01-01

    This paper studies how certain speculative transitions in financial markets can be ascribed to a symmetry break that happens in the collective decision making. Investors are assumed to be bounded rational, using a limited set of information including past price history and expectation on future dividends. Investment strategies are dynamically changed based on realized returns within a game theoretical scheme with Nash equilibria. In such a setting, markets behave as complex systems whose payoff reflect an intrinsic financial symmetry that guarantees equilibrium in price dynamics (fundamentalist state) until the symmetry is broken leading to bubble or anti-bubble scenarios (speculative state). We model such two-phase transition in a micro-to-macro scheme through a Ginzburg-Landau-based power expansion leading to a market temperature parameter which modulates the state transitions in the market. Via simulations we prove that transitions in the market price dynamics can be phenomenologically explained by the number of traders, the number of strategies and amount of information used by agents, all included in our market temperature parameter.

  12. Epidemiology and causation: a realist view.

    PubMed Central

    Renton, A

    1994-01-01

    In this paper the controversy over how to decide whether associations between factors and diseases are causal is placed within a description of the public health and scientific relevance of epidemiology. It is argued that the rise in popularity of the Popperian view of science, together with a perception of the aims of epidemiology as being to identify appropriate public health interventions, have focussed this debate on unresolved questions of inferential logic, leaving largely unanalysed the notions of causation and of disease at the ontological level. A realist ontology of causation of disease and pathogenesis is constructed within the framework of "scientific materialism", and is shown to provide a coherent basis from which to decide causes and to deal with problems of confounding and interaction in epidemiological research. It is argued that a realist analysis identifies a richer role for epidemiology as an integral part of an ontologically unified medical science. It is this unified medical science as a whole rather than epidemiological observation or experiment which decides causes and, in turn, provides a key element to the foundations of rational public health decision making.

    Lageard, Giovanni

    2011-01-01

    The aim of this paper is to carry out an analysis of the legal evolution in Italy of the assessment of causation i.e. cause and effect, in oncological diseases, a question taken into consideration by the High Court almost exclusively with reference to pleural mesothelioma. The most debated question when defining the causal association between asbestos exposure and mesothelioma is the possible role that any multiple potentially causative exposures could assume in the induction and development of the disease, and in particular the role of any asbestos exposure over the successive employment periods. Indeed, this is a subject on which, to date, no agreement has yet been reached in scientific doctrine: these divergences bear important practical significance from a legal point of view, since sustaining one thesis or another may constitute determining factors when ascertaining responsibility for individuals who, in the past, had decisional statuses in the workplace. Jurisprudence in the High Court took on an oscillating position on this question as from the early 2000s, which was divided into those who sustained the thesis of the relevance of any asbestos exposure over the successive employment periods and those who were of a different opinion, i.e. only the first exposure period has relevant causative effect. The point under discussion concerns, in particular, the adequacy of a probabilistic law only governing such a question. An important turning point was made in the year 2010 when two sentences were announced in the High Court, reiterating, in strict compliance with the principles affirmed by the United Sections in 2002, that a judge cannot, and must not, be satisfied with a general causation, but must rather reach a judgment on the basis of an individual causation. In particular, not only did the second of these two sentences recognise the multifactorial nature of mesothelioma, something which had almost always been denied in jurisprudence in the past, but it also

  15. Measuring market performance in restructured electricity markets: An empirical analysis of the PJM energy market

    NASA Astrophysics Data System (ADS)

    Tucker, Russell Jay

    2002-09-01

    Today the electric industry in the U.S. is transitioning to competitive markets for wholesale electricity. Independent system operators (ISOs) now manage broad regional markets for electrical energy in several areas of the U.S. A recent rulemaking by the Federal Energy Regulatory Commission (FERC) encourages the development of regional transmission organizations (RTOs) and restructured competitive wholesale electricity markets nationwide. To date, the transition to competitive wholesale markets has not been easy. The increased reliance on market forces coupled with unusually high electricity demand for some periods have created conditions amenable to market power abuse in many regions throughout the U.S. In the summer of 1999, hot and humid summer conditions in Pennsylvania, New Jersey, Maryland, Delaware, and the District of Columbia pushed peak demand in the PJM Interconnection to record levels. These demand conditions coincided with the introduction of market-based pricing in the wholesale electricity market. Prices for electricity increased on average by 55 percent, and reached the $1,000/MWh range. This study examines the extent to which generator market power raised prices above competitive levels in the PJM Interconnection during the summer of 1999. It simulates hourly market-clearing prices assuming competitive market behavior and compares these prices with observed market prices in computing price markups over the April 1-August 31, 1999 period. The results of the simulation analysis are supported with an examination of actual generator bid data of incumbent generators. Price markups averaged 14.7 percent above expected marginal cost over the 5-month period for all non-transmission-constrained hours. The evidence presented suggests that the June and July monthly markups were strongly influenced by generator market power as price inelastic peak demand approached the electricity generation capacity constraint of the market. While this analysis of the

    Blue-green algae and Dinoflagellate etc. are common types of phytoplankton as causative species which cause the harmful algal blooms (HABs). The growth process of causative species is complex according to the variation of the environmental disturbance such as the periodic factor in reality and recent studies have not revealed the secret of the growth complexity yet. Based on the empirical and theoretical results of the growth of causative species, a nonlinear controlled system with periodic factor was obtained and the different effects of the periodic factor on the control of the cell density and the growth rate of causative species were studied by three theorems using the norm theory and finite difference method. Simulations and experimental data were also used to assess the effectiveness of the controlled results.

    This study investigates the well-documented phenomenon of phase transition in financial markets using combined information from both return and volume changes within short time intervals. We suggest a new measure for the phase transition behaviour of markets, calculated as a return distribution conditional on local variance in volume imbalance, and show that this measure successfully captures phase transition behaviour under various conditions. We analyse the intraday trade and quote dataset from the KOSPI 200 index futures, which includes detailed information on the original order size and the type of each initiating investor. We find that among these two competing factors, the submitted order size yields more explanatory power on the phenomenon of market phase transition than the investor type.

    We present a model describing the competition between information transmission and decision making in financial markets. The solution of this simple model is recalled, and possible variations discussed. It is shown numerically that despite its simplicity, it can mimic a size effect comparable to a crash localized in time. Two extensions of this model are presented that allow to simulate the demand process. One of these extensions has a coherent stable equilibrium and is self-organized, while the other has a bistable equilibrium, with a spontaneous segregation of the population of agents. A new model is introduced to generate a transition between those two equilibriums. We show that the coherent state is dominant up to an equal mixing of the two extensions. We focus our attention on the microscopic structure of the investment rate, which is the main parameter of the original model. A constant investment rate seems to be a very good approximation.

  3. A cascading failure model for analyzing railway accident causation

    Liu, Jin-Tao; Li, Ke-Ping

    2018-01-01

    In this paper, a new cascading failure model is proposed for quantitatively analyzing the railway accident causation. In the model, the loads of nodes are redistributed according to the strength of the causal relationships between the nodes. By analyzing the actual situation of the existing prevention measures, a critical threshold of the load parameter in the model is obtained. To verify the effectiveness of the proposed cascading model, simulation experiments of a train collision accident are performed. The results show that the cascading failure model can describe the cascading process of the railway accident more accurately than the previous models, and can quantitatively analyze the sensitivities and the influence of the causes. In conclusion, this model can assist us to reveal the latent rules of accident causation to reduce the occurrence of railway accidents.

  4. Women's health status in Poland in the transition to a market economy.

    2002-03-01

    Since 1989 Poland has been experiencing large-scale social and economic changes as a result of the reforms associated with the transition to a market economy. This study uses a 1996 Health Survey of over 20,000 women to examine the impact of the new socio-economic situation and of women's multiple roles on their health at the early stage of transition. We investigated the importance of selected economic, socio-demographic and cultural determinants in explaining differences in women's health status in Poland, focusing on education level, (un)employment, living conditions, marital status, smoking and life style. There are health inequalities between men and women in Poland based on life expectancy, chronic diseases and health self-assessment. Some of these, especially the large differences between life expectancy at working ages, may be attributed to the difficult socio-economic situation. The multivariate analysis of women's self-assessed health and morbidity from selected chronic diseases indicated substantial inequalities in health. Together with the behavioural and cultural risk factors recognized by medicine, such as obesity, lack of physical exercise and smoking, the paper shows the crucial role of economic factors in influencing Polish women's health. Women whose financial position is poor are more likely to assess their health as less than good, to suffer from respiratory and circulatory systems' diseases and report neurotic problems. Other factors, strongly connected with the transition process in Poland, which contribute to health problems are lack of employment and low educational level, particularly for younger women. Women's marital and parental status are also important predictors of some categories of health problems; however, their influence varies for women of different ages. Our survey also supports the thesis that loneliness in old age, defined on the basis of living in a one-person household, may be negatively correlated with health status.

    Much analysis of youth transitions focuses on the first year after education, or outcomes at a specific age. Such work looks, for example, at the effect of education on the likelihood of being employed or unemployed. This study takes a different angle by considering the effect of education on the persistence of labour market outcomes. For example,…

  8. The Perfect Storm: Preterm Birth, Neurodevelopmental Mechanisms, and Autism Causation.

    2014-01-01

    A unifying model of autism causation remains elusive, and thus well-designed explanatory models are needed to develop appropriate therapeutic and preventive interventions. This essay argues that autism is not a static disorder, but rather an ongoing process. We discuss the link between preterm birth and autism and briefly review the evidence supporting the link between immune system characteristics and both prematurity and autism. We then propose a causation process model of autism etiology and pathogenesis, in which both neurodevelopment and ongoing/prolonged neuroinflammation are necessary pathogenetic component mechanisms. We suggest that an existing model of sufficient cause and component causes can be interpreted as a mechanistic view of etiology and pathogenesis and can serve as an explanatory model for autism causal pathways.

  12. The GRADE approach and Bradford Hill's criteria for causation.

    PubMed

    Schünemann, Holger; Hill, Suzanne; Guyatt, Gordon; Akl, Elie A; Ahmed, Faruque

    2011-05-01

    This article describes how the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to grading the quality of evidence and strength of recommendations considers the Bradford Hill criteria for causation and how GRADE may relate to questions in public health. A primary concern in public health is that evidence from non-randomised studies may provide a more adequate or best available measure of a public health strategy's impact, but that such evidence might be graded as lower quality in the GRADE framework. GRADE, however, presents a framework that describes both criteria for assessing the quality of research evidence and the strength of recommendations that includes considerations arising from the Bradford Hill criteria. GRADE places emphasis on recommendations and in assessing quality of evidence; GRADE notes that randomisation is only one of many relevant factors. This article describes how causation may relate to developing recommendations and how the Bradford Hill criteria are considered in GRADE, using examples from the public health literature with a focus on immunisation.

    Electricity systems are a central component of modern economies. Many electricity markets are transitioning from centrally regulated systems to decentralized markets. Furthermore, several electricity markets that have recently undergone this transition have exhibited extremely unsatisfactory results, most notably in California. These high stakes transformations require the introduction of largely untested regulatory structures. Suitable tools that can be used to test these regulatory structures before they are applied to real systems are required. Multi-agent models can provide such tools. To better understand the requirements such as tool, a live electricity market simulation was created. This experience helped to shape the developmentmore » of the multi-agent Electricity Market Complex Adaptive Systems (EMCAS) model. To explore EMCAS' potential, several variations of the live simulation were created. These variations probed the possible effects of changing power plant outages and price setting rules on electricity market prices.« less

    2011-02-01

    Head injuries are the most common serious injuries sustained by children in motor vehicle crashes and are of critical importance with regard to long-term disability. There is a lack of understanding of how seat belt-restrained children sustain head injuries in frontal impacts. The aim of the study was to identify the AIS2+ head injury causation scenarios for rear-seated, belt-restrained children in frontal impacts, including the set of parameters contributing to the injury. In-depth crash investigations from two National Highway Traffic Safety Administration (NHTSA) databases, the National Automotive Sampling System-Crashworthiness Data System (NASS-CDS; 1997-2008) and the Crash Injury Research and Engineering Network (CIREN; 1996-2009), were collected and analyzed in detail. Selection criteria were all frontal impacts with principal direction of force (PDOF) of 11, 12, and 1 o'clock involving rear-seated, three-point belt-restrained, with or without booster cushion, children from 3 to 13 years with an AIS2+ head injury. Cases were analyzed using the BioTab method of injury causation assessment in order to systematically analyze the injury causation scenario for each case. There were 27 cases meeting the inclusion criteria, 19 cases with MAIS2 head injuries and 8 cases with MAIS3+ head injuries, including 2 fatalities. Three major injury causation scenarios were identified, including head contact with seatback (10 cases), head contact with side interior (7 cases,) and no evidence of head contact (9 cases). Head injuries with seatback or side interior contact typically included a PDOF greater than 10 degree (similar to the Insurance Institute for Highway Safety [IIHS] and EuroNCAP offset frontal testing) and vehicle maneuvers. For seatback contact, the vehicle's movements contributed to occupant kinematics inboard the vehicle, causing a less than optimal restraint of the torso and/or torso roll out of the shoulder belt. For side interior contact, the PDOF and

    Study the intensity of formation of microbial biofilms by Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus strains isolated during various forms of pyelonephritis. 150 clinical isolates of microorganisms isolated from urine ofpatientswith acute and chronic pyelonephritiswere included into the study. Determination of intensity of film-formation was carried out by staining of the formed biofilms by crystal violet with consequent extraction of the dye and measurement of its concentration in washout solution. Among causative agents ofpyelonephritis P. aeruginosa isolates had the maximum film-forming ability. The intensity of biofilm formation of these isolates was 2-3 time higher than staphylococcus and enterobacteria strains. Strains isolated from patients with chronic pyelonephritis by ability to form biofilms significantly surpassed strains isolated from acute pyelonephritis patients. A higher ability to form microbial biofilms for microorganisms--causative agents of pyelonephritis progressing against the background ofurolithiasis was noted. The ability to form biofilms is determined by both causative agent species and character of the infectious process in which this microorganism participates. Intensive formation of biofilms by E. coli, P. aeruginosa, K. pneumoniae, S. aureus clinical isolates may be an important factor of chronization of urinary tract infections.

    2015-07-01

    An empirical and theoretical analysis of financial crises is conducted based on statistical mechanics in non-equilibrium physics. The transition probability provides a new tool for diagnosing a changing market. Both calm and turbulent markets can be described by the birth-death process for price movements driven by identical agents. The transition probability in a time window can be estimated from stock market indexes. Positive and negative feedback trading behaviors can be revealed by the upper and lower curves in transition probability. Three dynamic regimes are discovered from two time periods including linear, quasi-linear, and nonlinear patterns. There is a clear link between liberalization policy and market nonlinearity. Numerical estimation of a market turning point is close to the historical event of the US 2008 financial crisis.

    Two theoretical perspectives have dominated debates about the impact of development on gender stratification: modernization theory, which argues that gender inequalities decline with economic growth, and the "women in development" perspective, which argues that development may initially widen gender gaps. Analyzing cross-sectional surveys and time-series data from China, this article indicates the relevance of both perspectives: while girls' educational opportunities were clearly more responsive than boys' to better household economic circumstances, the era of market transition in the late 1970s and early 1980s failed to accelerate and, in fact, may have temporarily slowed progress toward gender equity.

  2. Communities, self-causation and the natural lottery.

    PubMed

    Loewy, E H

    1988-01-01

    This paper examines the various notions of community, and of the 'natural lottery' as well as investigating the role that 'self-causation' plays in communal obligations. In examining community, two opposing views are juxtaposed: (1) the view that community consists merely of persons united by duties of refraining from harm one to another, resulting in autonomy based justice which makes freedom an absolute condition of mortality; and (2) a broader view which sees the concept of community as entailing obligations of beneficence, resulting in beneficence based justice and which, therefore, sees freedom as a value to be cautiously traded with other values. In examining the 'natural lottery' in the light of community, the various consequences of viewing the lottery in various ways and the impact that our view of community has on these consequences, is explored. A third option, the option that the 'natural lottery' as the cause of illness and health is a shaky concept, is offered. Self-causation of illness and its linkage to concepts of community and of the 'natural lottery' is then briefly examined. It is concluded that (1) community implies a social contract which, in order to be conceived in the first place, necessitates more than a minimalist ethic: to come about, a degree of beneficence inspiring trust is presupposed; (2) conceiving community narrowly is neither what we ordinarily do when we think of the term nor, for that matter, workable in our world.(ABSTRACT TRUNCATED AT 250 WORDS)

    This report presents a microsimulation model of a transition economy. Transition is defined as the process of moving from a state-enterprise economy to a market economy. The emphasis is on growing a market economy starting from basic microprinciples. The model described in this report extends and modifies the capabilities of Aspen, a new agent-based model that is being developed at Sandia National Laboratories on a massively parallel Paragon computer. Aspen is significantly different from traditional models of the economy. Aspen`s emphasis on disequilibrium growth paths, its analysis based on evolution and emergent behavior rather than on a mechanistic view ofmore » society, and its use of learning algorithms to simulate the behavior of some agents rather than an assumption of perfect rationality make this model well-suited for analyzing economic variables of interest from transition economies. Preliminary results from several runs of the model are included.« less

    Market confidence is essential for successful investing. By incorporating multi-market into the evolutionary minority game, we investigate the effects of investor beliefs on the evolution of collective behaviors and asset prices. It is found that the roles of market confidence are closely related to whether or not there exists another market. When there exists another investment opportunity, different market confidence may lead to the same price fluctuations and the same investment attainment. There are two feedback effects. Being overly optimistic about a particular asset makes an investor become insensitive to losses. A delayed strategy adjustment leads to a decline in wealth and one's runaway from the market. The withdrawal of the agents results in the optimization of the strategy distributions and an increase in wealth. Being overly pessimistic about a particular asset makes an investor over-sensitive to losses. One's too frequent strategy adjustment leads to a decline in wealth. The withdrawal of the agents results in the improvement of the market environment and an increase in wealth.

  8. Etiology in psychiatry: embracing the reality of poly‐gene‐environmental causation of mental illness

    PubMed Central

    Uher, Rudolf; Zwicker, Alyson

    2017-01-01

    Intriguing findings on genetic and environmental causation suggest a need to reframe the etiology of mental disorders. Molecular genetics shows that thousands of common and rare genetic variants contribute to mental illness. Epidemiological studies have identified dozens of environmental exposures that are associated with psychopathology. The effect of environment is likely conditional on genetic factors, resulting in gene‐environment interactions. The impact of environmental factors also depends on previous exposures, resulting in environment‐environment interactions. Most known genetic and environmental factors are shared across multiple mental disorders. Schizophrenia, bipolar disorder and major depressive disorder, in particular, are closely causally linked. Synthesis of findings from twin studies, molecular genetics and epidemiological research suggests that joint consideration of multiple genetic and environmental factors has much greater explanatory power than separate studies of genetic or environmental causation. Multi‐factorial gene‐environment interactions are likely to be a generic mechanism involved in the majority of cases of mental illness, which is only partially tapped by existing gene‐environment studies. Future research may cut across psychiatric disorders and address poly‐causation by considering multiple genetic and environmental measures across the life course with a specific focus on the first two decades of life. Integrative analyses of poly‐causation including gene‐environment and environment‐environment interactions can realize the potential for discovering causal types and mechanisms that are likely to generate new preventive and therapeutic tools.

    2014-02-01

    In this paper, a new model is constructed for the causation analysis of railway accident based on the complex network theory. In the model, the nodes are defined as various manifest or latent accident causal factors. By employing the complex network theory, especially its statistical indicators, the railway accident as well as its key causations can be analyzed from the overall perspective. As a case, the “7.23” China—Yongwen railway accident is illustrated based on this model. The results show that the inspection of signals and the checking of line conditions before trains run played an important role in this railway accident. In conclusion, the constructed model gives a theoretical clue for railway accident prediction and, hence, greatly reduces the occurrence of railway accidents.

  11. Causation in negligence: from anti-jurisprudence to principle--individual responsibility as the cornerstone for the attribution of liability.

    PubMed

    Bagaric, Mirko; Erbacher, Sharon

    2011-06-01

    Causation is one of the most esoteric and poorly defined legal principles. The common law standards of the "but for" test and common sense are, in reality, code for unconstrained judicial choice. This leads to a high degree of unpredictability in negligence cases. Changes to the causation standard following the torts reforms have done nothing to inject principle into this area of law: the concept of "appropriateness" is no more illuminating than common sense. Despite this, the trend of recent High Court decisions offers some prospect of clarifying the test for causation. Key themes to emerge are an increased emphasis on individual responsibility and the associated concept of coherency with other legal standards. This article examines the doctrinal reasons underpinning the increasingly important role of these ideals and suggests how they can be accommodated into the test for causation to inject greater coherence and predictability into this area of law.

The relevance of the issue is related to the above-average performance of the pharmaceutical industry, its role in the generation of humanity's demographic transition, and specific development routes of marketing as a scientific and practical discipline. The sensitive nature of a pharmaceutical product on the one hand generates the intense legislation on this market, whereas on the other, the circumstances of its use generate a specific environment in which the production/consumption of the products of pharmaceutical industry is intensively reflected as a specific medical, cultural, economic and even political phenomenon.

    2016-01-01

    Aspergillosis is an important deep mycosis. The causative agents are Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, and Aspergillus terreus, of which A. fumigatus is the most prevalent. Cryptic Aspergillus spp., which morphologically resemble representative species of each Aspergillus section, also cause aspergillosis. Most of the cryptic species reveal different susceptibility patterns and/or different secondary metabolite profiles, also called exometabolome in this manuscript, from those representative species. On the other hand, azole-resistant A. fumigatus strains in clinical specimens and in the environment have been reported. Therefore, it is imperative to precisely identify the species, including cryptic Aspergillus spp., and evaluate the susceptibility of isolates.In this manuscript, some of the causative cryptic Aspergillus spp. are briefly reviewed. In addition, the exometabolome of Aspergillus section Fumigati is described. Finally, azole resistance of A. fumigatus is also discussed, in reference to several studies from Japan.

    Bacterial keratitis is a sight-threatening infection of the cornea that is one of the leading causes of blindness globally. In this report, we analyze the role of moxifloxacin susceptibility in the relationship between causative organisms and clinical outcome in bacteria keratitis. A mediation analysis is used to assess the role of moxifloxacin susceptibility in the relationship between causative organisms and clinical outcome in bacterial keratitis using data collected in a randomized, controlled trial. In the Steroids for Corneal Ulcers Trial (SCUT), 500 corneal infections were treated with topical moxifloxacin. The outcome of 3-week best spectacle-corrected visual acuity was significantly associated with an organism (Streptococcus pneumoniae, Pseudomonas aeruginosa, etc., P = 0.008). An indirect effects mediation model suggests that MIC accounted for approximately 13% (95% confidence interval, 3%-24%, P = 0.015) of the effect of the organism on 3-week visual acuity. Moxifloxacin mediates the relationship between causative organisms and clinical outcome in bacterial keratitis, and is likely on the causal pathway between the organism and outcome.

    PubMed

    Weatherall, M; Ioannides, S; Braithwaite, I; Beasley, R

    2015-01-01

    A better understanding of the causation of asthma and allergic disorders could potentially lead to intervention strategies that reduce their prevalence and severity. One potential causative factor is the use of paracetamol. Most of the evidence for the link with asthma is from non-experimental studies of paracetamol exposure in utero, infancy, childhood and adult life; however, it has been difficult to rule out confounding and bias in the associations observed. The two randomized clinical trials of the effect of paracetamol in patients with asthma have been difficult to interpret, due to methodological issues. There have been no randomized controlled trials of paracetamol use and the development of asthma. Both asthma and paracetamol use are common, and so even if there is a relatively small effect of paracetamol exposure on the development of asthma or its severity, then such an effect would be of major public health significance. It is proposed that randomized controlled trials of the effect of paracetamol on the development of asthma and its severity are a high research priority. © 2014 John Wiley & Sons Ltd.

    For decades, the question of social selection vs social causation has been raised by public health researchers and social scientists to explain the association between socioeconomic factors and mood disorders.(1,2) The social selection or "downward drift" theory postulates that the disease itself limits an individual's educational and occupational achievements, leading to a lower socioeconomic status (SES). In contrast, the social causation hypothesis suggests that factors associated with low SES (e.g., stressful life events, poor health care access) increase the likelihood of disease onset or prolonged disease duration.(3,4) Simply stated, the end result of each hypothesis is as follows:

  20. Understanding Financial Market States Using an Artificial Double Auction Market

    PubMed Central

    2016-01-01

    The ultimate value of theories describing the fundamental mechanisms behind asset prices in financial systems is reflected in the capacity of such theories to understand these systems. Although the models that explain the various states of financial markets offer substantial evidence from the fields of finance, mathematics, and even physics, previous theories that attempt to address the complexities of financial markets in full have been inadequate. We propose an artificial double auction market as an agent-based model to study the origin of complex states in financial markets by characterizing important parameters with an investment strategy that can cover the dynamics of the financial market. The investment strategies of chartist traders in response to new market information should reduce market stability based on the price fluctuations of risky assets. However, fundamentalist traders strategically submit orders based on fundamental value and, thereby stabilize the market. We construct a continuous double auction market and find that the market is controlled by the proportion of chartists, Pc. We show that mimicking the real state of financial markets, which emerges in real financial systems, is given within the range Pc = 0.40 to Pc = 0.85; however, we show that mimicking the efficient market hypothesis state can be generated with values less than Pc = 0.40. In particular, we observe that mimicking a market collapse state is created with values greater than Pc = 0.85, at which point a liquidity shortage occurs, and the phase transition behavior is described at Pc = 0.85.

We show that mimicking the real state of financial markets, which emerges in real financial systems, is given within the range Pc = 0.40 to Pc = 0.85; however, we show that mimicking the efficient market hypothesis state can be generated with values less than Pc = 0.40. In particular, we observe that mimicking a market collapse state is created with values greater than Pc = 0.85, at which point a liquidity shortage occurs, and the phase transition behavior is described at Pc = 0.85.

  5. Stress fractures of the ribs and upper extremities: causation, evaluation, and management.

    PubMed

    Miller, Timothy L; Harris, Joshua D; Kaeding, Christopher C

    2013-08-01

    Stress fractures are common troublesome injuries in athletes and non-athletes. Historically, stress fractures have been thought to predominate in the lower extremities secondary to the repetitive stresses of impact loading. Stress injuries of the ribs and upper extremities are much less common and often unrecognized. Consequently, these injuries are often omitted from the differential diagnosis of rib or upper extremity pain. Given the infrequency of this diagnosis, few case reports or case series have reported on their precipitating activities and common locations. Appropriate evaluation for these injuries requires a thorough history and physical examination. Radiographs may be negative early, requiring bone scintigraphy or MRI to confirm the diagnosis. Nonoperative and operative treatment recommendations are made based on location, injury classification, and causative activity. An understanding of the most common locations of upper extremity stress fractures and their associated causative activities is essential for prompt diagnosis and optimal treatment.

  6. Multi-Sided Markets for Transforming Healthcare Service Delivery.

    Kuziemsky, Craig; Vimarlund, Vivian

    2018-01-01

    Changes in healthcare delivery needs have necessitated the design of new models for connecting providers and consumers of services. While healthcare delivery has traditionally been a push market, multi-sided markets offer the potential for transitioning to a pull market for service delivery. However, there is a need to better understand the business model for multi-sided markets as a first step to using them in healthcare. This paper addressed that need and describes a multi-sided market evaluation framework. Our framework identifies patient, governance and service delivery as three levels of brokerage consideration for evaluating multi-sided markets in healthcare.

  8. Exploring inattention and distraction in the SafetyNet Accident Causation Database.

    Talbot, Rachel; Fagerlind, Helen; Morris, Andrew

    2013-11-01

    Distraction and inattention are considered to be very important and prevalent factors in the causation of road accidents. There have been many recent research studies which have attempted to understand the circumstances under which a driver becomes distracted or inattentive and how distraction/inattention can be prevented. Both factors are thought to have become more important in recent times partly due to the evolution of in-vehicle information and communication technology. This study describes a methodology that was developed to understand when factors such as distraction and inattention may have been contributors to crashes and also describes some of the consequences of distraction and inattention in terms of subsequent driver actions. The study uses data relating to distraction and inattention from the SafetyNet Accident Causation Database. This database was formulated as part of the SafetyNet project to address the lack of representative in-depth accident causation data within the European Union. Data were collected in 6 European countries using 'on-scene' and 'nearly on-scene' crash investigation methodologies. 32% of crashes recorded in the database, involved at least one driver, rider or pedestrian, who was determined to be 'Inattentive' or 'Distracted'. 212 of the drivers were assigned 'Distraction' and 140 drivers were given the code 'Inattention'. It was found that both distraction and inattention often lead to missed observations within the driving task and consequently 'Timing' or 'Direction' become critical events in the aetiology of crashes. In addition, the crash types and outcomes may differ according to the type and nature of the distraction and inattention as determined by the in-depth investigations. The development of accident coding methodology is described in this study as is its evolution into the Driver Reliability and Error Analysis Model (DREAM) version 3.0. Copyright © 2012 Elsevier Ltd.

  9. [Changes in labor market participation of older employees in Germany: the perspective of labor market research].

    PubMed

    Brussig, M

    2009-08-01

    For many years, Germany has been regarded in international comparisons as an example of a generous early retirement culture, resulting in a low labor market participation of older employees. Recently, however, employment rates of older employees have increased remarkably. Reasons are the demographic structure of older persons in Germany, a long-term trend of increasing female labor market participation, and reforms in labor-market policies and pension policies during the last 10 years. Despite an increasing labor market participation of older employees, traditional labor market risks for older persons partly remained, but some new risks evolved as well. Therefore, social differentiation among older employees increased.Although detailed macro descriptions exist, the causes of labor market developments cannot be fully understood with cross-sectional data alone. An important stimulus is to be expected from individual longitudinal data which reflect employment histories and labor market transitions such as employment exit and retirement.

  10. Financial instability from local market measures

    Bardoscia, Marco; Livan, Giacomo; Marsili, Matteo

    2012-08-01

    We study the emergence of instabilities in a stylized model of a financial market, when different market actors calculate prices according to different (local) market measures. We derive typical properties for ensembles of large random markets using techniques borrowed from statistical mechanics of disordered systems. We show that, depending on the number of financial instruments available and on the heterogeneity of local measures, the market moves from an arbitrage-free phase to an unstable one, where the complexity of the market—as measured by the diversity of financial instruments—increases, and arbitrage opportunities arise. A sharp transition separates the two phases. Focusing on two different classes of local measures inspired by real market strategies, we are able to analytically compute the critical lines, corroborating our findings with numerical simulations.

    This report describes the results of an effort to identify key analytic issues associated with modeling a transition to hydrogen as a fuel for light duty vehicles, and using insights gained from this effort to suggest ways to improve ongoing modeling efforts. The study reported on here examined multiple hydrogen scenarios reported in the literature, identified modeling issues associated with those scenario analyses, and examined three DOE-sponsored hydrogen transition models in the context of those modeling issues. The three hydrogen transition models are HyTrans (contractor: Oak Ridge National Laboratory), MARKAL/DOE* (Brookhaven National Laboratory), and NEMS-H2 (OnLocation, Inc). The goals ofmore » these models are (1) to help DOE improve its R&D effort by identifying key technology and other roadblocks to a transition and testing its technical program goals to determine whether they are likely to lead to the market success of hydrogen technologies, (2) to evaluate alternative policies to promote a transition, and (3) to estimate the costs and benefits of alternative pathways to hydrogen development.« less

    Chiropractors claim to locate, analyze and diagnose a putative spinal lesion known as subluxation and apply the mode of spinal manipulation (adjustment) for the correction of this lesion. The purpose of this examination is to review the current evidence on the epidemiology of the subluxation construct and to evaluate the subluxation by applying epidemiologic criteria for it's significance as a causal factor. The databases of PubMed, Cinahl, and Mantis were searched for studies using the keywords subluxation, epidemiology, manipulation, dose-response, temporality, odds ratio, relative risk, biological plausibility, coherence, and analogy. The criteria for causation in epidemiology are strength (strength of association), consistency, specificity, temporality (temporal sequence), dose response, experimental evidence, biological plausibility, coherence, and analogy. Applied to the subluxation all of these criteria remain for the most part unfulfilled. There is a significant lack of evidence to fulfill the basic criteria of causation. This lack of crucial supportive epidemiologic evidence prohibits the accurate promulgation of the chiropractic subluxation.

  16. How emotion shapes behavior: feedback, anticipation, and reflection, rather than direct causation.

    PubMed

    Baumeister, Roy F; Vohs, Kathleen D; DeWall, C Nathan; Zhang, Liqing

    2007-05-01

    Fear causes fleeing and thereby saves lives: this exemplifies a popular and common sense but increasingly untenable view that the direct causation of behavior is the primary function of emotion. Instead, the authors develop a theory of emotion as a feedback system whose influence on behavior is typically indirect. By providing feedback and stimulating retrospective appraisal of actions, conscious emotional states can promote learning and alter guidelines for future behavior. Behavior may also be chosen to pursue (or avoid) anticipated emotional outcomes. Rapid, automatic affective responses, in contrast to the full-blown conscious emotions, may inform cognition and behavioral choice and thereby help guide current behavior. The automatic affective responses may also remind the person of past emotional outcomes and provide useful guides as to what emotional outcomes may be anticipated in the present. To justify replacing the direct causation model with the feedback model, the authors review a large body of empirical findings.

  18. Coupled effects of market impact and asymmetric sensitivity in financial markets

    Zhong, Li-Xin; Xu, Wen-Juan; Ren, Fei; Shi, Yong-Dong

    2013-05-01

    By incorporating market impact and asymmetric sensitivity into the evolutionary minority game, we study the coevolutionary dynamics of stock prices and investment strategies in financial markets. Both the stock price movement and the investors’ global behavior are found to be closely related to the phase region they fall into. Within the region where the market impact is small, investors’ asymmetric response to gains and losses leads to the occurrence of herd behavior, when all the investors are prone to behave similarly in an extreme way and large price fluctuations occur. A linear relation between the standard deviation of stock price changes and the mean value of strategies is found. With full market impact, the investors tend to self-segregate into opposing groups and the introduction of asymmetric sensitivity leads to the disappearance of dominant strategies. Compared with the situations in the stock market with little market impact, the stock price fluctuations are suppressed and an efficient market occurs. Theoretical analyses indicate that the mechanism of phase transition from clustering to self-segregation in the present model is similar to that in the majority-minority game and the occurrence and disappearance of efficient markets are related to the competition between the trend-following and the trend-aversion forces. The clustering of the strategies in the present model results from the majority-wins effect and the wealth-driven mechanism makes the market become predictable.

  19. Neurological and neuropsychological consequences of electrical and lightning shock: review and theories of causation

    PubMed Central

    Andrews, Christopher J.; Reisner, Andrew D.

    2017-01-01

    Injuries from lightning and electrical injuries involve multiple systems of the body, however neurological symptoms are very widely reported. A disabling neuropsychological syndrome is also noted. This paper presents a comprehensive review of neurological and neuropsychological symptoms. Partial theories of causation for these injuries have been advanced, however, there is no convincing explanation for both delay in onset of symptoms and also the genesis of the neuropsychological syndrome. A theory of causation is proposed which satisfies both these constraints. This theory suggests circulating hormones such as cortisol, together with nitric oxide and oxidant free radicals from glutamatergic hyper-stimulation, act on tissues remote from the injury path including the hippocampus. This theory opens a research path to explore treatment options. PMID:28616016

    Treatment of acute lymphoblastic leukaemia (ALL) using intensive chemotherapy has resulted in high cure rates but also substantial morbidity. Infective complications represent a significant proportion of treatment-related toxicity. The objective of this study was to describe the microbiological aetiology and clinical outcome of episodes of chemotherapy-induced febrile neutropaenia in a cohort of children treated for ALL at our institution. Patients with ALL were treated with either the HKSGALL93 or the Malaysia-Singapore (Ma-Spore) 2003 chemotherapy protocols. The records of 197 patients who completed the intensive phase of treatment, defined as the period of treatment from induction, central nervous system (CNS)-directed therapy to reinduction from June 2000 to January 2010 were retrospectively reviewed. There were a total of 587 episodes of febrile neutropaenia in 197 patients, translating to an overall rate of 2.98 episodes per patient. A causative pathogen was isolated in 22.7% of episodes. An equal proportion of Gram-positive bacteria (36.4%) and Gram-negative bacteria (36.4%) were most frequently isolated followed by viral pathogens (17.4%), fungal pathogens (8.4%) and other bacteria (1.2%). Fungal organisms accounted for a higher proportion of clinically severe episodes of febrile neutropaenia requiring admission to the high-dependency or intensive care unit (23.1%). The overall mortality rate from all episodes was 1.5%. Febrile neutropaenia continues to be of concern in ALL patients undergoing intensive chemotherapy. The majority of episodes will not have an identifiable causative organism. Gram-positive bacteria and Gram-negative bacteria were the most common causative pathogens identified. With appropriate antimicrobial therapy and supportive management, the overall risk of mortality from febrile neutropaenia is extremely low.

    2018-01-01

    Recent developments in neuroaesthetics have heightened the need for causative approaches to more deeply understand the mechanism underlying perception, emotion, and aesthetic experiences. This has recently been the topic for empirical work, employing several causative methods for changing brain activity, as well as comparative assessments of individuals with brain damage or disease. However, one area of study with high potential, and indeed a long history of often nonscientific use in the area of aesthetics and art, employing psychopharmacological chemicals as means of changing brain function, has not been systematically utilized. This chapter reviews the literature on this topic, analyzing neuroendocrinological (neurochemical) approaches and mechanisms that might be used to causatively study the aesthetic brain. We focus on four relevant neuromodulatory systems potentially related to aesthetic experience: the dopaminergic, serotonergic, cannabinoid, and the opioidergic system. We build a bridge to psychopharmacological methods and review drug-induced behavioral and neurobiological consequences. We conclude with a discussion of hypotheses and suggestions for future research. © 2018 Elsevier B.V. All rights reserved.

    Nachev and Hacker's conceptual analysis of the neural antecedents of voluntary action underscores the real danger of ignoring the meta-theoretical apparatus of cognitive neuroscience research. In this response, we temper certain claims (e.g., whether or not certain research questions are incoherent), consider a more extreme consequence of their argument against cognitive neuroscience (i.e., whether or not one can speak about causation with neural antecedents at all), and, finally, highlight recent methodological developments that exemplify cognitive neuroscientists' focus on studying the brain as a parallel, dynamic, and highly complex biological system.

    2014-05-01

    Russia provides an interesting context for studying the labor market experiences of the elderly because of its experience with market transition, its looming growth in the elderly dependency ratio, and its unusual pension policies that do not penalize pensioners for working. We use data from twenty surveys of the Russian population conducted from February 1991 to November 2007 to analyze the labor market participation and earnings of elderly Russians following market transition. Economic desperation, exacerbated by low pension levels, pushed some elderly to seek employment for income on the labor market. Elderly Russians with more education had more opportunities to work, and education differentials increased as market reforms progressed. The correlates of earnings operate similarly for retirement- and pre-retirement age Russians, with several exceptions: unobserved factors favoring employment are negatively associated with earnings for the elderly, occupation mediates most of the effects of education, and patterns of change over time differ somewhat. Elderly Russians are not disproportionately blocked from employment following market reforms. Following the initial transition shock, their labor market activity increased. Overall, both push and pull factors shape the employment and earnings of the elderly, affecting different segments of them. Copyright © 2013 Elsevier Inc. All rights reserved.

    Study the manifestations of epidemic process and leading transmission routes of causative agents of enterovirus serous meningitis (SM) by results of laboratory studies and epidemiologic examination of epidemic nidi. During 2010 - 2014 a study for enterovirus was carried out in cerebrospinal fluid in 743 patients, hospitalized into medical organizations of Perm with primary diagnosis "serous meningitis", feces of 426 individuals, that had communicated with patients with SM of enterovirus etiology; 827 water samples from the distribution network, 295 water samples from open water and 57 washes from surface of vegetables and fruits. All the samples were studied in polymerase chain reaction, part--by a virological method. Epidemiologic examination of 350 epidemic nidi of SM was carried out. Enterovirus and (or) its RNA were detected in 62.0% of patients and 61.9% of individuals that had communicated with patients with enteroviris SM. ECHO 6 serotype enterovirus dominated among the causative agents. Maximum intensity of epidemic process of enterovirus SM, based on data from laboratory examination of patients, was detected in a group of organized pre-school and school age children during summer-autumn period. . Examination of epidemic nidi and laboratory control of environmental objects have shown that CV causative agent transmission factors are, in particular, unboiled water from decentralized sources (boreholes, wells, springs), water from open waters during bathing, as well as fresh vegetables, fruits, berries and meals produced from them. .

    Having secure employment, in contrast to being unemployed, is regarded as an important determinant of health. Research and theories about the negative health consequences of unemployment indicated that transition from unemployment to a paid job could lead to improved health. The objective of this study was to test the hypothesis that obtaining permanent employment after being in an unstable labour market position protects mental health. A 14-year follow-up of all graduates from compulsory school in an industrial town in northern Sweden was performed at ages 16, 18, 21 and 30 years. Complete data on the cohort were collected for 1044 individuals with the aid of a comprehensive questionnaire. The response rate was 96.4%. The health measurement used in this study was the psychological symptoms analysed by multivariate logistic regression. Those who obtained permanent employment were the focus of the analysis. This group consisted of people who were in an unstable labour market position for a year or more between the ages of 25 and 29, and who had acquired a permanent job one year before and at the time of the investigation. After controlling for gender as well as for an indicator of health-related selection, possible confounders and mediators, an association was found between the lower probability of psychological symptoms and obtaining permanent employment (OR = 0.35, 95% CI 0.19-0.63) as well as having permanent employment (OR = 0.22, 95% CI 0.10-0.51). Our findings suggest that transition from an unstable labour market position to permanent employment could be health-promoting, even after controlling for possible confounders and mediators, as well as for an indicator of health-related selection. However, as there are few studies in the field, there is a need for more longitudinal studies in order to further analyse the relationship and to examine possible explanations.

    Mass mortality that is acompanied by reddish browning of the soft tissues has been occurring in cultured pearl oyster, Pinctada fucata martensii. The disease is called Akoya oyster disease (AOD). Although spreading pattern of the disease and transmission experiments suggest that the disease is infectious, the causative agent has not yet been identified. We used shotgun and 16S rRNA-based metagenomic analysis to identify genes that are present specifically in affected oysters. The genes found only in diseased oysters were mostly bacterial origin, suggesting that the causative agent was a bacterial pathogen. This hypothesis was supported by the inhibition of AOD development in naïve oysters injected with the hemolymph of diseased animals followed immediately with penicillin bath-administration. Further analyses of the hemolymph and mantle specifically and universally detected genes of bacteria that belong to phylum Spirochaetes in diseased pearl oysters but not in healthy oysters. By in situ hybridization or immunostaining, a Brachyspira-like bacterium was observed in the smears of hemolymph from affected oysters, but not from healthy oysters. Phylogenetic analysis using 16S rRNA sequences showed that the presumptive causative bacterium was outside of but most closely related to family Brachyspiraceae. We propose ‘Candidatus Maribrachyspira akoyae’ gen. nov, sp nov., for this bacterium. PMID:28771537

    There is the general philosophical question concerning the relationship between physics, which is often taken to be our fundamental and all-encompassing science, on one hand and the special sciences, such as biology and psychology, each of which deals with phenomena in some specially restricted domain, on the other. This paper deals with a narrower question: Are there laws in the special sciences, laws like those we find, or expect to find, in basic physics? Three arguments that are intended to show that there are no such laws are presented and examined. The paper ends with brief remarks concerning the implications of these arguments for explanation and causation in the special sciences.

  17. Top-down causation by information control: from a philosophical problem to a scientific research programme

    Auletta, G; Ellis, G.F.R; Jaeger, L

    2008-01-01

    It has been claimed that different types of causes must be considered in biological systems, including top-down as well as same-level and bottom-up causation, thus enabling the top levels to be causally efficacious in their own right. To clarify this issue, the important distinctions between information and signs are introduced here and the concepts of information control and functional equivalence classes in those systems are rigorously defined and used to characterize when top-down causation by feedback control happens, in a way that is testable. The causally significant elements we consider are equivalence classes of lower level processes, realized in biological systems through different operations having the same outcome within the context of information control and networks.

    Deep infection remains a serious complication of orthopaedic surgery. Knowledge of infection rates and causative organisms is important to guide infection control measures. The aim of the present study was to determine infection rates and causative organisms in elective shoulder surgery. Cases complicated by infection were identified and prospectively recorded over a 2-year period. All patients undergoing elective shoulder surgery in the concurrent period at a single Specialist Upper Limb Unit in the UK were identified from the hospital electronic database. In total, 1574 elective shoulder cases were performed: 1359 arthroscopic (540 with implant insertion) and 215 open (197 with implant insertion). The overall infection rate in open surgery of 2.5% was significantly higher than arthroscopic implant cases at 0.7% ( p  < 0.005). The overall infection rate in implant arthroscopic surgery was significantly higher at 0.7% compared to 0% in non-implant related surgery. ( p  < 0.05). Patients undergoing open shoulder surgery have a significantly higher risk of infection compared to arthroscopic shoulder surgery. Arthroscopic surgery with implant insertion has a statistically significantly higher risk of developing deep infection compared to procedures with no implant insertion. We recommend prophylactic antibiotics in open shoulder surgery and arthroscopic shoulder surgery with implant insertion.

  19. Observational goals for Max '91 to identify the causative agent for impulsive bursts

    1989-01-01

    Recent studies of impulsive hard x ray and microwave bursts suggest that a propagating causative agent with a characteristic velocity of the order of 1000 km/s is responsible for these bursts. The results of these studies are summarized and observable distinguishing characteristics of the various possible agents are highlighted, with emphasis on key observational goals for the Max '91 campaigns. The most likely causative agents suggested by the evidence are shocks, thermal conduction fronts, and propagating modes of magnetic reconnection in flare plasmas. With new instrumentation planned for Max '91, high spatial resolution observations of hard x ray sources have the potential to identify the agent by revealing detailed features of source spatial evolution. Observations with the Very Large Array and other radio imaging instruments are of great importance, as well as detailed modeling of coronal loop structures to place limits on their density and temperature profiles. With the combined hard x ray and microwave imaging observations, aided by loop model results, the simplest causative agent to rule out would be the propagating modes of magnetic reconnection. To fit the observational evidence, reconnection modes would need to travel at approximately the same velocity (the Alfven velocity) in different coronal structures that vary in length by a factor of 10(exp 3). Over such a vast range in loop lengths, it is difficult to believe that the Alfven velocity is constant. Thermal conduction fronts would be suggested by sources that expand along the direction of B and exhibit relatively little particle precipitation. Particle acceleration due to shocks could produce more diverse radially expanding source geometries with precipitation at loop footprints.

  20. Sensation seekers as a healthcare marketing metasegment.

    Self, Donald R; Findley, Carolyn Sara

    2010-01-01

    This article discusses "sensation seekers" as a market segment for communication and prevention programs for various lifestyle and/or risk-related health problem areas such as alcohol abuse, drug abuse, suicide attempts, and sexually transmitted diseases. Although sensation seekers tend to be creative, artistic individuals, they are also prone to various negative health behaviors and many population-based prevention programs have over-looked these individuals as an important target. Various inputs to sensation-seeking causation are explored, including biological/chemical, psychological, and the impact of external characteristics. Using a combination for regulatory focus and risk homeostasis, propositions are provided for improving the effectiveness of the communications. Recommendations for prevention efforts focusing on reaching this subculture using television, along with other electronic media are proposed, including recommendations for message construction and presentation venues.

    Viable practices change with the professional and personal needs of dentists and with trends in society. There is no single way for transitioning out of practice--concluding a direct sale, remaining as an associate, and even purchasing a new practice to better match one's more mature lifestyle and practiced preferences. Changing ratios of dentists to patients currently favor a seller's market and emergence of corporate models provide new options. An analysis is given of the Canadian practice market. Planning advice is also offered.

    In a product market or stock market, different products or stocks compete for the same consumers or purchasers. We propose a method to estimate the time-varying transition matrix of the product share using a multivariate time series of the product share. The method is based on the assumption that each of the observed time series of shares is a stationary distribution of the underlying Markov processes characterized by transition probability matrices. We estimate transition probability matrices for every observation under natural assumptions. We demonstrate, on a real-world dataset of the share of automobiles, that the proposed method can find intrinsic transition of shares. The resulting transition matrices reveal interesting phenomena, for example, the change in flows between TOYOTA group and GM group for the fiscal year where TOYOTA group's sales beat GM's sales, which is a reasonable scenario.

  6. Practical aspects of treatment with target specific anticoagulants: initiation, payment and current market, transitions, and venous thromboembolism treatment.

    PubMed

    Mahan, Charles E

    2015-04-01

    Target specific anticoagulants (TSOACs) have recently been introduced to the US market for multiple indications including venous thromboembolism (VTE) prevention in total hip and knee replacement surgeries, VTE treatment and reduction in the risk of stroke in patients with non-valvular atrial fibrillation (NVAF). Currently, three TSOACs are available including rivaroxaban, apixaban, and dabigatran with edoxaban currently under Food and Drug Administration review for VTE treatment and stroke prevention in NVAF. The introduction of these agents has created a paradigm shift in anticoagulation by considerably simplifying treatment and anticoagulant initiation for patients by giving clinicians the opportunity to use a rapid onset, rapid offset, oral agent. The availability of these rapid onset TSOACs is allowing for outpatient treatment of low risk pulmonary embolism and deep vein thrombosis which can greatly reduce healthcare costs by avoiding inpatient hospitalizations and treatment for the disease. Additionally with this practice, the complications of an inpatient hospitalization may also be avoided such as nosocomial infections. Single-agent approaches with TSOACs represent a paradigm shift in the treatment of VTE versus the complicated overlap of a parenteral agent with warfarin. Transitions between anticoagulants, including TSOACs, are a high-risk period for the patient, and clinicians must carefully consider patient characteristics such as renal function as well as the agents that are being transitioned. TSOAC use appears to be growing slowly with improved payment coverage throughout the US.

  8. Critical slowing down associated with regime shifts in the US housing market

    Complex systems are described by a large number of variables with strong and nonlinear interactions. Such systems frequently undergo regime shifts. Combining insights from bifurcation theory in nonlinear dynamics and the theory of critical transitions in statistical physics, we know that critical slowing down and critical fluctuations occur close to such regime shifts. In this paper, we show how universal precursors expected from such critical transitions can be used to forecast regime shifts in the US housing market. In the housing permit, volume of homes sold and percentage of homes sold for gain data, we detected strong early warning signals associated with a sequence of coupled regime shifts, starting from a Subprime Mortgage Loans transition in 2003-2004 and ending with the Subprime Crisis in 2007-2008. Weaker signals of critical slowing down were also detected in the US housing market data during the 1997-1998 Asian Financial Crisis and the 2000-2001 Technology Bubble Crisis. Backed by various macroeconomic data, we propose a scenario whereby hot money flowing back into the US during the Asian Financial Crisis fueled the Technology Bubble. When the Technology Bubble collapsed in 2000-2001, the hot money then flowed into the US housing market, triggering the Subprime Mortgage Loans transition in 2003-2004 and an ensuing sequence of transitions. We showed how this sequence of couple transitions unfolded in space and in time over the whole of US.

  9. Three essays on price dynamics and causations among energy markets and macroeconomic information

    NASA Astrophysics Data System (ADS)

    Hong, Sung Wook

    This dissertation examines three important issues in energy markets: price dynamics, information flow, and structural change. We discuss each issue in detail, building empirical time series models, analyzing the results, and interpreting the findings. First, we examine the contemporaneous interdependencies and information flows among crude oil, natural gas, and electricity prices in the United States (US) through the multivariate generalized autoregressive conditional heteroscedasticity (MGARCH) model, Directed Acyclic Graph (DAG) for contemporaneous causal structures and Bernanke factorization for price dynamic processes. Test results show that the DAG from residuals of out-of-sample-forecast is consistent with the DAG from residuals of within-sample-fit. The result supports innovation accounting analysis based on DAGs using residuals of out-of-sample-forecast. Second, we look at the effects of the federal fund rate and/or WTI crude oil price shock on US macroeconomic and financial indicators by using a Factor Augmented Vector Autoregression (FAVAR) model and a graphical model without any deductive assumption. The results show that, in contemporaneous time, the federal fund rate shock is exogenous as the identifying assumption in the Vector Autoregression (VAR) framework of the monetary shock transmission mechanism, whereas the WTI crude oil price return is not exogenous. Third, we examine price dynamics and contemporaneous causality among the price returns of WTI crude oil, gasoline, corn, and the S&P 500. We look for structural break points and then build an econometric model to find the consistent sub-periods having stable parameters in a given VAR framework and to explain recent movements and interdependency among returns. We found strong evidence of two structural breaks and contemporaneous causal relationships among the residuals, but also significant differences between contemporaneous causal structures for each sub-period.

    Livestock keeping is regarded as a store of wealth for pastoralists in Kenya, besides their social and cultural functions. The objective of this study was to prioritize constraints to cattle marketing in a semiarid pastoral area of Narok in Kenya and to analyze efficiency of cattle marketing in transit markets located in Garissa, Kajiado and Narok counties. Primary data collection from traders was done through participatory interviews and market surveys, while time series market price data were obtained from secondary sources. Five focus group interviews were organized with a total of 61 traders in markets from Narok County, while a total of 187 traders who purchased cattle from transit markets provided data on a number of cattle purchased, purpose of purchase, buying prices and mode of transport. Market performance was analyzed through trader's market share, gross margins, Gini coefficient and coefficient of correlation between time series price data. The marketing constraints which were ranked high included lack of market for meat, trekking of cattle to markets, lack of price information and occurrence of diseases. About 10 % of traders purchased over 50 % of cattle which were supplied in markets, revealing a high concentration index. Further, a gross marketing margin per cattle purchased was positive in all markets revealing profitability. Moderate correlation coefficients existed between time series market price data for cattle purchased from Ewaso Ngiro and Mulot markets (r = 0.5; p < 0.05), while those between Dagoretti and Garissa markets were weak (r = 0.2; p > 0.05). The integration of markets, occurrence of diseases and trekking of cattle to markets are factors which may increase a risk of infectious disease spread. These results call for support of disease surveillance activities within markets in pastoral areas so that farms and systems which are connected are protected from threats of infectious diseases.

    2015-01-01

    The mitochondrial permeability transition (PT) – an abrupt increase permeability of the inner membrane to solutes – is a causative event in ischemia–reperfusion injury of the heart, and the focus of intense research in cardioprotection. The PT is due to opening of the PT pore (PTP), a high conductance channel that is critically regulated by a variety of pathophysiological effectors. Very recent work indicates that the PTP forms from the F-ATP synthase, which would switch from an energy-conserving to an energy-dissipating device. This review provides an update on the current debate on how this transition is achieved, and on the PTP as a target for therapeutic intervention. This article is part of a Special Issue entitled "Mitochondria: from basic mitochondrial biology to cardiovascular disease". PMID:25268651

    In developed economies, the sign of the price increment influences the volatility in an asymmetric fashion—negative increments tend to result in larger volatility (increments with larger magnitudes), while positive increments result in smaller volatility. We explore whether this asymmetry extends from developed economies to European transition economies and, if so, how such asymmetry changes over time as these transition economies develop and mature. We analyze eleven European transition economies and compare the results with those obtained by analyzing U.S. market indices. Specifically, we calculate parameters that quantify both the volatility asymmetry and the strength of its dependence on prior increments. We find that, like their developed economy counterparts, almost all transition economy indices exhibit a significant volatility asymmetry, and the parameter γ characterizing asymmetry fluctuates more over time for transition economies. We also investigate how the association between volatility and volatility asymmetry varies by type of market. We test the hypothesis of a negative correlation between volatility and volatility asymmetry. We find that, for developed economies, γ experiences local minima during (i) “Black Monday” on October 19, 1987, (ii) the dot-com bubble crash in 2002, and (iii) the 2007-2009 global crisis while for transition economies, γ experiences local maxima during times of economic crisis.

    We find numerical and empirical evidence for dynamical, structural and topological phase transitions on the (German) Frankfurt Stock Exchange (FSE) in the temporal vicinity of the worldwide financial crash. Using the Minimal Spanning Tree (MST) technique, a particularly useful canonical tool of the graph theory, two transitions of the topology of a complex network representing the FSE were found. The first transition is from a hierarchical scale-free MST representing the stock market before the recent worldwide financial crash, to a superstar-like MST decorated by a scale-free hierarchy of trees representing the market’s state for the period containing the crash. Subsequently, a transition is observed from this transient, (meta)stable state of the crash to a hierarchical scale-free MST decorated by several star-like trees after the worldwide financial crash. The phase transitions observed are analogous to the ones we obtained earlier for the Warsaw Stock Exchange and more pronounced than those found by Onnela-Chakraborti-Kaski-Kertész for the S&P 500 index in the vicinity of Black Monday (October 19, 1987) and also in the vicinity of January 1, 1998. Our results provide an empirical foundation for the future theory of dynamical, structural and topological phase transitions on financial markets.

    Dilated cardiomyopathy (DCM) and malignant ventricular arrhythmias are important causes of congestive heart failure, heart transplantation, and sudden cardiac death in young patients. Cypher/ZASP is a cytoskeletal protein localized in the sarcomeric Z-line that has a pivotal role in maintaining adult cardiac structure and function. The putative mutation p.(D117N) in Cypher/ZASP has been suggested to cause systolic dysfunction, dilated left ventricle with hypertrabeculated myocardium, and intraventricular conduction disturbance, based on two reported sporadic cases. In two unrelated Bedouin families, one with pediatric DCM and the other with DCM and ventricular arrhythmias at young adulthood searching for the causative mutation by exome sequencing we identified the p.(D117N) variant in Cypher/ZASP. However, p.(D117N) did not segregate as the causative mutation in these families, i.e. it was not present in some patients and was found in several individuals who had no clinical manifestations. Furthermore, the carrier frequency in the Bedouin population of origin is estimated to be 5.2%, which is much higher than the incidence of idiopathic DCM in this population. Thus, our data support the notion that the p.(D117N) variant in Cypher/ZASP is not a causative mutation in the families tested by us. The results also indicates that at least in some cases, the p.(D117N) in Cypher/ZASP is not a causative mutation and the role of D117N in Cypher/ZASP in cardiac pathologies should be further clarified and re-evaluated.

    Tinea capitis is endemic among schoolchildren in tropical Africa. The objective was to determine the prevalence of symptomatic tinea capitis in schoolchildren in Gabon. A cross-sectional study was conducted with 454 children aged 4-17 years, attending a rural school and an urban school. The diagnosis of tinea capitis was based on clinically manifest infection, direct microscopic examination using 20% potassium hydroxide (KOH) solution and fungal culture. Based on clinical examination, 105 (23.1%) of 454 children had tinea capitis. Seventy-four (16.3%) children were positive by direct examination (KOH) and/or fungal culture. The prevalence of tinea capitis depended on the school studied and ranged from 20.4% in the urban school with a higher socioeconomic status to 26.3% in the rural school with a lower socioeconomic status. Similarly, the spectrum of causative species varied between the different schools. Taken the schools together, Trichophyton soudanense (29.4%) was the most prominent species, followed by Trichophyton tonsurans (27.9%) and Microsporum audouinii (25.0%). Clinically manifest tinea capitis is endemic among schoolchildren in the Lambaréné region in Gabon. The prevalence of tinea capitis and the causative species depended on the type of school that was investigated. © 2010 Blackwell Verlag GmbH.

    Tianshui City is one of the mountainous cities that are threatened by severe geo-hazards in Gansu Province, China. Statistical probability models have been widely used in analyzing and evaluating geo-hazards such as landslide. In this research, three approaches (Certainty Factor Method, Weight of Evidence Method and Information Quantity Method) were adopted to quantitively analyze the relationship between the causative factors and the landslides, respectively. The source data used in this study are including the SRTM DEM and local geological maps in the scale of 1:200,000. 12 causative factors (i.e., altitude, slope, aspect, curvature, plan curvature, profile curvature, roughness, relief amplitude, and distance to rivers, distance to faults, distance to roads, and the stratum lithology) were selected to do correlation analysis after thorough investigation of geological conditions and historical landslides. The results indicate that the outcomes of the three models are fairly consistent.

    Foot dermatitis refers to the predominant involvement of feet in the eczematous process. This study is undertaken to determine the clinical pattern and causative agent in foot eczema and to evaluate the role of patch testing in determining the causative agent of foot eczema. Data was collected from 50 patients with foot eczema, who attended the out-patient department. The patch test was performed using Indian standard series. Patch test was positive in 88% of the patients. The most common site affected was the dorsal aspect of the foot (48%) and scaly plaque was the predominant morphological pattern. The highest number of patients (24%) showed positive reactions to mercaptobenzothiazole (MBT) and the lowest (4%) to neomycin sulfate. Rubber and rubber chemicals have been reported worldwide to be the most common sensitizer causing foot eczema. Thus, patch test has a major role in finding out the cause of foot eczema.

    The understanding of complex systems has become a central issue because such systems exist in a wide range of scientific disciplines. We here focus on financial markets as an example of a complex system. In particular we analyze financial data from the S&P 500 stocks in the 19-year period 1992-2010. We propose a definition of state for a financial market and use it to identify points of drastic change in the correlation structure. These points are mapped to occurrences of financial crises. We find that a wide variety of characteristic correlation structure patterns exist in the observation time window, and that these characteristic correlation structure patterns can be classified into several typical ``market states''. Using this classification we recognize transitions between different market states. A similarity measure we develop thus affords means of understanding changes in states and of recognizing developments not previously seen.

    The understanding of complex systems has become a central issue because such systems exist in a wide range of scientific disciplines. We here focus on financial markets as an example of a complex system. In particular we analyze financial data from the S&P 500 stocks in the 19-year period 1992-2010. We propose a definition of state for a financial market and use it to identify points of drastic change in the correlation structure. These points are mapped to occurrences of financial crises. We find that a wide variety of characteristic correlation structure patterns exist in the observation time window, and that these characteristic correlation structure patterns can be classified into several typical "market states". Using this classification we recognize transitions between different market states. A similarity measure we develop thus affords means of understanding changes in states and of recognizing developments not previously seen.

    Cost overrun is an increase of cost of project from approved budget which was signed by parties at the time of tender. Cost overrun in construction of highway projects is a common problem worldwide and construction industry of Pakistan is also facing this crucial problem of cost overrun in highway projects of Pakistan. The main objective of this research is to identify the causative factors of cost overrun in highway projects of Sindh province of Pakistan. A well designed questionnaire was developed based on 64 common factors of cost overrun from literature review. Developed questionnaire was distributed among selected 30 experts from owner/client, designer/consultant and contractor who have experience more than 20 years’ experience in highway projects. The collected data was statistical analyzed. After analysis results showed that delay process in payment by client, inadequate planning, client interference, poor contract management, delay of decision making, change of scope of project and financial problems faced by client were most causative factors of cost overrun in highway projects. This research will provide alertness to stakeholders of highway projects of Sindh province to avoid cost overrun in projects.

    Since the attribution of the Nobel prize in 2002 to Kahneman for prospect theory, behavioral finance has become an increasingly important subfield of finance. However the main parts of behavioral finance, prospect theory included, understand financial markets through individual investment behavior. Behavioral finance thereby ignores any interaction between participants. We introduce a socio-financial model (Vitting Andersen J. and Nowak A., An Introduction to Socio-Finance (Springer, Berlin) 2013) that studies the impact of communication on the pricing in financial markets. Considering the simplest possible case where each market participant has either a positive (bullish) or negative (bearish) sentiment with respect to the market, we model the evolution of the sentiment in the population due to communication in subgroups of different sizes. Nonlinear feedback effects between the market performance and changes in sentiments are taken into account by assuming that the market performance is dependent on changes in sentiments (e.g., a large sudden positive change in bullishness would lead to more buying). The market performance in turn has an impact on the sentiment through the transition probabilities to change an opinion in a group of a given size. The idea is that if for example the market has observed a recent downturn, it will be easier for even a bearish minority to convince a bullish majority to change opinion compared to the case where the meeting takes place in a bullish upturn of the market. Within the framework of our proposed model, financial markets stylized facts such as volatility clustering and extreme events may be perceived as arising due to abrupt sentiment changes via ongoing communication of the market participants. The model introduces a new volatility measure which is apt of capturing volatility clustering and from maximum-likelihood analysis we are able to apply the model to real data and give additional long term insight into where a market is

    1980-01-01

    The difference in operating environment and in construction between escalators in transit and nontransit use, the impact of recent escalator innovations, and areas which could benefit from urban mass transportation administration sponsored research and development are determined. Several factors causing a more severe transit escalator operating environment are identified. There are no significant design differences between transit and nontransit escalators. Recent innovations that have affected performance and cost include outdoor escalators, extra flat steps at both landings, and modular escalators. Data were collected by interviews at transit agencies. Long term, unscheduled, escalator maintenance records were available for analysis from one property. A description of escalator operating principles is provided. Transit represents less than 5% of the U.S. escalator market. Transit agencies have limited leverage on escalator industry practices. A substantial impact on transit escalator cost and performance can be achieved by research identifying when and how to apply and specify several of the more recent innovations. Purchase of escalators under long term (25 year) maintenance contracts is one method that has been used to promote escalators manufactured for minimum life cycle cost.

  12. Causation mechanisms in car-to-vulnerable road user crashes: implications for active safety systems.

    PubMed

    Habibovic, Azra; Davidsson, Johan

    2012-11-01

    Vulnerable road users (VRUs), such as pedestrians and bicyclists, are often involved in crashes with passenger cars. One way to prevent these crashes is to deploy active safety systems that support the car drivers and/or VRUs. However, to develop such systems, a thorough understanding of crash causation mechanisms is required. The aim of this study is to identify crash causation mechanisms from the perspective of the VRUs, and to explore the implications of these mechanisms for the development of active safety systems. Data originate from the European project SafetyNet, where 995 crashes were in-depth investigated using the SafetyNet Accident Causation System (SNACS). To limit the scope, this study analyzed only intersection crashes involving VRUs. A total of 56 VRU crashes were aggregated. Results suggest that, while 30% of the VRUs did not see the conflict car due to visual obstructions in the traffic environment, 70% of the VRUs saw the car before the collision, but still misunderstood the traffic situation and/or made an inadequate plan of action. An important implication that follows from this is that, while detection of cars is clearly an issue that needs to be addressed, it is even more important to help the VRUs to correctly understand traffic situation (e.g., does the driver intend to slow down, and if s/he does, is it to let the VRU cross or for some other reason?). The former issue suggests a role for various cooperative active safety systems, as the obstacles are generally impenetrable with regular sensors. The latter issue is less straightforward. While various systems can be proposed, such as providing gap size estimation and reducing the car speed variability, the functional merits of each such a system need to be further investigated.

    This study investigated independent risk factors and causative organisms in microbial keratitis in daily disposable contact lens (CL)-wearers. A multisite prospective case-control study was undertaken. Cases were daily disposable CL-wearers attending Moorfields Eye Hospital with microbial keratitis and those reported through a one-year surveillance study in Australia and in New Zealand. A population-based telephone survey identified daily disposable CL-wearing controls. Subjects completed a questionnaire describing CL-wear history, hygiene and demographics. The sample used for risk factor analysis was weighted in proportion to the CL-wearing population at each location. Corneal scrape results were accessed. Independent risk factors were determined using multiple binary logistic regression. Causative organisms in different CL-wear modalities were compared using a chi-squared test. 963 daily disposable CL-wearers were identified, from which 67 cases and 374 controls were sampled. Independent risk factors were; wearing CLs every day compared with less frequent use (OR 10.4x; 95% CI 2.9-56.4), any overnight wear (OR 1.8x; 95% CI 1.6-2.1), less frequent hand washing (OR 1.8x; 95% CI 1.6-2.0), and smoking (OR 1.3x; 95% CI 1.1-1.6). Certain daily disposable CLs (OR 0.2x; 95% CI 0.1-0.2) had protective effects. Environmental organisms were less frequently recovered with daily disposable CLs (20%), compared with other modalities (36%; p<0.02). Overnight wear, increased exposure in daily wear, smoking and poor hand hygiene are significant risk factors for microbial keratitis with daily disposable CLs. Risk varied with daily disposable CL type. The profile of causative organisms is consistent with less severe disease.

    Mental illnesses account for 20% of the total burden of disease in China. Yet, health policy in China has not devoted much attention to mental health problems and their impact on Chinese society. The objective of this paper is to investigate the impact of mental health status on labour market outcomes, such as employment and income, and provide evidence about some of the economic consequences of mental illnesses. Using the China Health Surveillance Baseline 2001 Survey and an instrumental variables estimation approach, we address possible reverse causation between work and mental health. To estimate the impact of self-reported mental health status, we use the two-part model, the first part estimating a logit equation for the probability of being employed and the second-part estimating an ordinary least squares (OLS) model on the log of individual income condition on being employed. We use a list of symptoms of mental disorders to constitute a measure of mental health status. Our identification strategy relies on instruments that measure average mental health status by zip code other than the observed individual to implement an instrumental variables model. Both men and women suffer a significant reduction in the employment rate and annual income if the average mental health deteriorates at a population level. The mental health index has a positive and significant effect on the likelihood of being employed. Our findings are consistent with what has been found in industrialised countries. This is the first empirical study that reveals that poor mental health status can be disruptive of labour market activities in China. A rapid rise of mental and behavioural problems in population reflects the transition to a market economy and indicates pressing problems that have gone unrecognised and unaddressed. The negative economic consequences in labour market outcomes suggest a potential gain from preventing and curing the mental disorder. Our study about the impact of mental

    2016-09-01

    In 1963, the Nobel Prize-winning ethologist Niko Tinbergen proposed a framework for the scientific study of animal behaviour by outlining four questions that should be answered to have a complete understanding: causation, ontogeny, function and evolution. At present, Tinbergen's framework is still considered the best way to guide animal behavioural research. Given the importance in science instruction of demonstrating how scientists work and ask questions, we investigated to what extent Tinbergen's questions are addressed in biology textbooks in secondary education in Flanders, Belgium, and represented in upper-secondary and first-year university students' explanations of behaviour in general and of specific animal behaviours. Our results revealed that teaching of animal behaviour mainly addresses ontogeny and causation, and that Tinbergen's framework is not explicitly referred to. Students typically addressed only one or two questions, with the majority addressing causation or both causation and ontogeny when explaining behaviour in general, but function or causation and function when explaining specific animal behaviours. This high prevalence of function may be due to teleological thinking. Evolution was completely neglected, even in university students who had recently completed an evolution course. Our results revealed that transfer of the concepts of ontogeny and evolution was (almost) absent. We argue why Tinbergen's framework should be an integral part of any biology curriculum.

    In this paper, the writers reviewed in detail the pharmaceutical market and the shifts in manufacturing and sales including the trade balance in Japan over a thirty-year period from 1980 to 2010. From the 1980s to the 1990s, many innovative pharmaceutical products were developed and launched in the Japanese market. During the same period, some Japanese companies managed to develop their first internationally marketable drugs, which were antibiotics and effective remedies for the digestive and circulatory organs. During this period, Japanese pharmaceutical companies were also able to launch some of blockbuster drugs. For two decades, the pharmaceutical market grew rapidly. For this reason, it can be called "The Growth Period for Pharmaceutical Products" in Japan. After that period, drug development and sales slowed down due to a lack of expertise in genetic engineering and biotechnologies. This situation caused a large deficit in the trade balance for Japanese pharmaceutical products. However, with regard to the trade balance (including technical royalties) for pharmaceutical product technologies, Japan remains in the black even today.

NAS (1) has called for the careful application of systems analysis tools to structure the complex assessment required. Others, raising cautionary notes, question whether a consistent and plausible transition to hydrogen light-duty vehicles can identified (2) and whether that transition would, on balance, be environmentally preferred. Modeling the market transition to hydrogen-powered vehicles is an inherently complex process, encompassing hydrogen production, delivery and retailing, vehicle manufacturing, and vehicle choice and use. We describe the integration of key technological and market factors in a dynamic transitionmore » model, HyTrans. The usefulness of HyTrans and its predictions depends on three key factors: (1) the validity of the economic theories that underpin the model, (2) the authenticity with which the key processes are represented, and (3) the accuracy of specific parameter values used in the process representations. This paper summarizes the theoretical basis of HyTrans, and highlights the implications of key parameter specifications with sensitivity analysis.« less

    In this paper we continue the study of the simulated stock market framework defined by the driving sentiment processes. We focus on the market environment driven by the buy/sell trading sentiment process of the Markov chain type. We apply the methodology of the Hidden Markov Models and the Recurrent Neural Networks to reconstruct the transition probabilities matrix of the Markov sentiment process and recover the underlying sentiment states from the observed stock price behavior. We demonstrate that the Hidden Markov Model can successfully recover the transition probabilities matrix for the hidden sentiment process of the Markov Chain type. We also demonstrate that the Recurrent Neural Network can successfully recover the hidden sentiment states from the observed simulated stock price time series.

    Most enterovirus surveillance studies lack detailed clinical data, which limits their clinical usefulness. This study aimed to describe the clinical spectrum and outcome of severe enterovirus infections in children, and to determine whether there are associations between causative enterovirus genotypes and clinical phenotypes. Retrospective analysis of microbiological and clinical data from a tertiary children's hospital in the South of England over a 17-month period (2012-2013). In total, 30 patients were identified, comprising sepsis (n = 9), myocarditis (n = 8), meningitis (n = 8) and encephalitis (n = 5). Cases with sepsis or myocarditis were significantly younger than those with central nervous system disease (median age 21 and 15 days vs. 79 days; P = 0.0244 and P = 0.0310, respectively). There was considerable diversity in the causative genotypes in each of the clinical phenotypes, with some predominance of echoviruses in the meningitis group, and coxsackie B viruses in the myocarditis group. Thirteen cases required mechanical ventilation, 11 cases inotropic support, 3 cases dialysis and 3 cases extracorporal membrane oxygenation. The overall mortality was 10% (sepsis group, n = 1; myocarditis group, n = 2). Of the survivors, 5 (19%) had long-term sequelae (myocardial dysfunction, n = 2; neurological sequelae, n = 3). Patients with encephalitis had the longest hospital stay (median: 16 days), compared with 9, 6 and 3 days in patients with myocarditis, sepsis and meningitis, respectively (P = 0.005). Enterovirus infections, particularly enteroviral myocarditis and encephalitis, can cause significant morbidity and mortality. The results show that there are currently no strong associations between clinical phenotypes and particular causative enterovirus genotypes in the South of England.

    2005-06-01

    To examine the role of foreign direct investment (FDI) in the nutrition transition, focusing on highly processed foods. Data on FDI were identified from reports/databases and then compiled and analysed. A review of published literature on FDI into the food sector was conducted. The nutrition transition is a public health concern owing to its connection with the rising burden of obesity and diet-related chronic diseases in developing countries. Global health leaders are calling for action to address the threat. Highly processed foods often have considerable fat, sugar and salt content, and warrant closer examination. FDI into food processing, service and retail has risen rapidly since the 1980s, mainly from transnational food companies (TFCs) in developed countries. As FDI has risen, so has the proportion invested in highly processed foods for sale in the host market. FDI has proved more effective than trade in generating sales of highly processed foods, and enables TFCs to cut costs, gain market power and obtain efficiencies in distribution and marketing. The amount of FDI targeted at developing countries is increasing; while a disproportionate share enters the larger developing economies, foreign affiliates of TFCs are among the largest companies in low- and low- to middle-income countries. The effect of FDI is to make more highly processed foods available to more people. FDI has made it possible to lower prices, open up new purchasing channels, optimise the effectiveness of marketing and advertising, and increase sales. FDI has been a key mechanism in shaping the global market for highly processed foods. Notwithstanding the role of demand-side factors, it has played a role in the nutrition transition by enabling and promoting the consumption of these foods in developing countries. Empirical data on consumption patterns of highly processed foods in developing countries are critically needed, but since FDI is a long-term investment vehicle, it is reasonable to

    The study examines employment prospects of persons who participate in further and re-training measures in the context of vocational rehabilitation in the responsibility of the Federal Employment Agency (FEA). Using administrative data of the FEA (RehaPro), we focus on persons completing vocational rehabilitation between 2009 and 2012 (N=21,772). We employ event history analysis to present time and extent of employment transition and their sustainability. By using multivariate analyses, factors for taking up employment are identified. Within 500 days, 70 % of promoted persons gain contributed employment, often directly after rehabilitation. The median for employment duration within the observation period is 670 days. Further training measures are an important opportunity for the re-integration of persons with health limitations in the labour market. © Georg Thieme Verlag KG Stuttgart · New York.

  16. The Chinese health care regulatory institutions in an era of transition.

    PubMed

    Fang, Jing

    2008-02-01

    The purpose of this paper is to contribute to a better understanding of Chinese health care regulation in an era of transition. It describes the major health care regulatory institutions operating currently in China and analyzes the underlying factors. The paper argues that in the transition from a planned to a market economy, the Chinese government has been employing a hybrid approach where both old and new institutions have a role in the management of emerging markets, including the health care market. This approach is consistent with the incremental reform strategy adopted by the Party-state. Although a health care regulatory framework has gradually taken shape, the framework is incomplete, with a particular lack of emphasis on professional self-regulation. In addition, its effectiveness is limited despite the existence of many regulatory institutions. In poor rural areas, the effectiveness of the regulatory framework is further undermined or distorted by the extremely difficult financial position that local governments find themselves in. The interpretations of the principle of 'rule of law' by policy makers and officials at different levels and the widespread informal network of relations between known individuals (Guanxi) play an important role in the operation of the regulatory framework. The findings of this paper reveal the complex nature of regulating health care in transitional China.

    Labour force participation rates of women differ strongly by ethnic origin. Even though existing research using cross-sectional studies has demonstrated that part of these differences can be attributed to compositional differences in human capital, household conditions and gender attitudes, residual 'ethnic effects' typically remain. To further our understanding of women's labour market behaviour across ethnic groups, we use a large-scale longitudinal study and apply a dynamic perspective to examine how far relevant life-course events in addition to individual characteristics, gender attitudes and religiosity contribute to the explanation of ethnic differences in women's labour force entries and exits in the UK. Our findings show that, adjusting for all these factors, Indian and Caribbean women do not differ from White majority women in their labour force entry and exit probabilities but that Pakistani and Bangladeshi women are less likely to enter and more likely to exit the labour market, whereas Black African women have higher entry rates. We also find that relations between life-course events and labour market transitions differ by ethnic group. Most notably, Pakistani and Bangladeshi women's labour market transitions are less sensitive to child-bearing and Caribbean women's transitions less sensitive to partnership changes than other women's.

    2017-01-26

    Understanding perceptions of the causes of ill-health common in indigenous communities may help policy makers to design effective integrated primary health care strategies to serve these communities. This study explored the indigenous beliefs of ill-health causation among those living in the Tehuledere Woreda /district/ in North East Ethiopia from a socio-cultural perspective. The study employed a qualitative ethnographic method informed by Murdock's Theory of Illness. Participatory observation, over a total of 5 months during the span of one year, was supplemented by focus group discussions (n = 96 participants in 10 groups) and in-depth interviews (n = 20) conducted with key informants. Data were analyzed thematically using narrative strategies. In these communities, illness is perceived to have supernatural (e.g., almighty God/ Allah, nature spirits, and human agents of the supernatural), natural (e.g., environmental sanitation and personal hygiene, poverty, biological and psychological factors) and societal causes (e.g., social trust, experiences of family support and harmony; and violation of social taboos). Therefore, the explanatory model of illness causation in this community was very similar to that of the Murdock model with one key difference: social elements need to be added to the model. Members of the study community believes that supernatural, natural and social elements are linked to ill-health causation. A successful integrated primary health care strategy should include strategies for supporting patients' needs in all three of these domains.

    An ehrlichia was consistently isolated from the peripheral blood leukocyte fraction of ponies that had been experimentally infected with Potomac horse fever by whole blood transfusion from naturally infected horses. The organism was propagated in a human histiocyte cell line for 3 to 5 weeks and then inoculated intravenously or intradermally into healthy adult ponies. Clinical signs of Potomac horse fever, which varied in the degree of severity, occurred 9 to 14 days post-inoculation in all of the ponies. One pony died 20 days post-inoculation. The ehrlichial organism was reisolated in the human histiocyte cell line from the blood leukocyte fraction of all of the experimental ponies on each day that samples were examined (days 9, 10, 11, 19, and 39). These organisms were identical to those originally detected in the wall of the intestine of ponies with clinically diagnosed Potomac horse fever when compared by light and electron microscopy and an immunofluorescence labeling technique. The immunofluorescent antibody titer became positive in a pony at 20 days postinjection. These results indicate that the ehrlichial organisms is the causative agent of Potomac horse fever.

  3. Beliefs about causation of schizophrenia: do Indian families believe in supernatural causes?

    2001-03-01

    Beliefs about the causation of schizophrenia could influence the attitudes patients' families adopt towards the patient and may also influence their help-seeking behaviour. Indian families have been typically described as often believing in causes like supernatural forces and therefore seeking help from magico-religious healers. In the changing mental health scenario in India, this impression needs verification. Key relatives living with 254 chronic schizophrenia patients were interviewed and asked to name the causes they believed were behind the illness. A list of possible causes was provided for the families to select from, and relatives were also encouraged to mention other possible causes, not featured in the list. The possible causes identified and the factors related to attributions made were analysed. A supernatural cause was named by only 12% of the families and as the only cause by 5%. Psychosocial stress was most commonly cited cause, followed by personality defect and heredity. A small number of families (14%) could not name any cause and 39% named more than one cause. Patient gender and education, duration of illness and the key relative's education and the nature of relationship were related to the type of causal attributions made. Families living with patients suffering chronic schizophrenia receiving treatment in urban India rarely subscribe to the idea of supernatural causation of the illness. The causal attributions made by them are fairly rational and understandable, given the relative lack of exposure to proper information about the illness.

  4. Management of busbar costs and spending tradeoffs for the transition to competitive markets in electricity

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Corio, M.R.; Boyd, G.

    Competition is changing the fundamental basis for doing business in the electricity generation market. As the market moves toward competitive market conditions, electricity will be viewed increasingly as a commodity--not only supplied to customers within a utility`s service area, but brokered and marketed outside its area as well. With movement toward retail wheeling being considered in California, Michigan, and New York, it may soon become a reality as well. This means that a utility can no longer feel secure as the monopoly supplier of electricity within its own franchise area. To remain the main supplier in its current service areamore » and compete for customers in other service areas, utilities will need to understand and examine all the components of ``busbar costs`` at its generating units. As competition drives the market to marginal costs, generating units with costs exceeding the market clearing price for electricity may soon have a limited role in the generation market. As the industry evolves, competition in the marketplace will force uneconomic plants to reduce costs or go out of business. This paper discusses results of studies addressing the evaluation of cost effectiveness, benchmarking of cost-efficiency, and development of marginal cost curves for busbar costs based on the development and aggregation of the three key measures which determine the cost and level of output (generation): (1) reliability; (2) heat rate; and (3) planned outage factor.« less

  5. Application of fault tree approach for the causation mechanism of urban haze in Beijing--Considering the risk events related with exhausts of coal combustion.

    Haze weather has become a serious environmental pollution problem which occurs in many Chinese cities. One of the most critical factors for the formation of haze weather is the exhausts of coal combustion, thus it is meaningful to figure out the causation mechanism between urban haze and the exhausts of coal combustion. Based on above considerations, the fault tree analysis (FAT) approach was employed for the causation mechanism of urban haze in Beijing by considering the risk events related with the exhausts of coal combustion for the first time. Using this approach, firstly the fault tree of the urban haze causation system connecting with coal combustion exhausts was established; consequently the risk events were discussed and identified; then, the minimal cut sets were successfully determined using Boolean algebra; finally, the structure, probability and critical importance degree analysis of the risk events were completed for the qualitative and quantitative assessment. The study results proved that the FTA was an effective and simple tool for the causation mechanism analysis and risk management of urban haze in China. Copyright © 2015 Elsevier B.V.

    Numerous studies have investigated the association between education and overweight/obesity. Yet less is known about the relative importance of causation (i.e. the influence of education on risks of overweight/obesity) and selection (i.e. the influence of overweight/obesity on the likelihood to attain education) hypotheses. A systematic review was performed to assess the linkage between education and overweight/obesity in prospective studies in general populations. Studies were searched within five databases, and study quality was appraised with the Newcastle-Ottawa scale. In total, 31 studies were considered for meta-analysis. Regarding causation (24 studies), the lower educated had a higher likelihood (odds ratio: 1.33, 1.21-1.47) and greater risk (risk ratio: 1.34, 1.08-1.66) for overweight/obesity, when compared with the higher educated. However, these associations were no longer statistically significant when accounting for publication bias. Concerning selection (seven studies), overweight/obese individuals had a greater likelihood of lower education (odds ratio: 1.57, 1.10-2.25), when contrasted with the non-overweight or non-obese. Subgroup analyses were performed by stratifying meta-analyses upon different factors. Relationships between education and overweight/obesity were affected by study region, age groups, gender and observation period. In conclusion, it is necessary to consider both causation and selection processes in order to tackle educational inequalities in obesity appropriately. © 2017 World Obesity Federation.

  10. The Regime Shift Associated with the 2004–2008 US Housing Market Bubble

    PubMed Central

    2016-01-01

    The Subprime Bubble preceding the Subprime Crisis of 2008 was fueled by risky lending practices, manifesting in the form of a large abrupt increase in the proportion of subprime mortgages issued in the US. This event also coincided with critical slowing down signals associated with instability, which served as evidence of a regime shift or phase transition in the US housing market. Here, we show that the US housing market underwent a regime shift between alternate stable states consistent with the observed critical slowing down signals. We modeled this regime shift on a universal transition path and validated the model by estimating when the bubble burst. Additionally, this model reveals loose monetary policy to be a plausible cause of the phase transition, implying that the bubble might have been deflatable by a timely tightening of monetary policy.

  13. Longitudinal linkages between perceived social support and posttraumatic stress symptoms: sequential roles of social causation and social selection.

    PubMed

    2008-06-01

    The authors examined social causation and social selection explanations for the association between perceptions of social support and psychological distress. Data came from a sample of 557 victims of natural disaster in Mexico. Structural equation modeling analyses indicated that social causation (more social support leading to less posttraumatic stress disorder [PTSD]) explained the support-to-distress relationship in the earlier postdisaster phase, 6 to 12 months after the impact. Both causal mechanisms emerged as significant paths in the midpoint of the study (12 and 18 months). Only social selection (more PTSD leading to less social support) accounted for the support-to-distress relationship at 18 to 24 months after the event. Interpersonal and social dynamics of disasters may explain why these two contrasting causal mechanisms emerged over time.

    Peritonitis before peritoneal dialysis (PD) training (pretraining peritonitis [PTP]) is an uncommon event. The study aim was to examine the causative organisms, clinical outcomes, risk factors, and long-term consequences of PTP. In this single-center, retrospective, observational study involving all incident patients on PD who developed PTP between 1998 and 2012, we examined the causative organisms, primary response rate, complete cure rate, risk factors, and associations of PTP with peritoneal equilibration test (PET) and patient survival. For each patient in the PTP group, the patients who underwent catheter insertion immediately before and after the index case were identified as controls. Among 1252 incident patients on PD, 52 (4.2%) patients developed PTP, and 104 patients were identified as controls. The two groups were similar in age, sex distribution, comorbidities, and residual renal function, but the PTP group had significantly lower hemoglobin and serum albumin. Patients were followed up for a median of 37.5 months (interquartile range [IQR], 16.3-62.2 months). The most common causative organisms of PTP were Staphylococcus aureus (30.8%) and polymicrobial (21.2%); 25% had negative growth. The primary response and complete cure rates were 82.7% and 78.8%, respectively. In the PTP group, 7.7% of patients died, 9.6% of patients required catheter removal, and PD training was significantly delayed (median =42.0; IQR, 26.0-65.8 days versus 27.5; IQR, 23.0-35.0 days; P=0.01). Multivariate logistic regression analysis showed that serum albumin was the only predictor of PTP (adjusted odds ratio, 0.89 per 1-g/dl increase; 95% confidence interval, 0.82 to 0.97). There were no differences in PET results and dialysis adequacy (measured around 1 month after PD training). The PTP group had significantly worse patient survival (median =41.2; IQR, 21.8-60.5 months versus 55.8; IQR, 40.4-71.2 months; P=0.02). Technique failure occurred in 11.5% and 10.6% of patients in the

It will also allow some portions of the radiofrequency spectrum used for broadcasting to be returned for public safety and commercial uses. The Congress set December 2006 as the target date for completing the DTV transition and turning the analog broadcast signals. However, this date can be extended if fewer than 85 percent of households in a market are able to receive the digital signals.

    Malignant pleural mesothelioma (MPM) is a lethal malignancy strongly associated with occupational exposure to asbestos. The aims of this study were to assess the quality of counseling provided to patients with MPM about the causation of MPM and the potential for compensation. The authors conducted a structured retrospective chart review of patients with a diagnosis of MPM. They abstracted demographic data, occupational and environmental history and exposure data. They also searched for documentation of patient education and counseling. The authors identified 16 patients with a new diagnosis of MPM during the study period. A job title was documented at least once in the records of 12 (75%) patients. Documentation of occupational exposure to asbestos was found in the records of 12 (75%) patients. Two patients (13%) were presumed to have had bystander exposure to asbestos. Education about MPM causation and counseling about opportunities for compensation were documented in the record of 1 patient (6%). Among patients with MPM, documentation of some elements of an occupational history, including an occupational asbestos exposure history, was common. Advice to pursue compensation for potential occupation related MPM was rare. Physicians may be missing opportunities to provide beneficial information to patients with newly diagnosed MPM regarding potential legal redress and compensation.

  19. From Snow to Hill to ALS: An epidemiological odyssey in search of ALS causation.

    PubMed

    Armon, Carmel

    2018-05-21

    Establishing mechanisms of disease causation in neurodegenerative diseases has long seemed to be beyond the pale of traditional epidemiological tools. Establishing a plausible mechanism for initiation of amyotrophic lateral sclerosis (ALS) has appeared a particularly elusive goal. This review shows that a likely mechanism for ALS initiation may be inferred by applying classical methods of epidemiological inference. Advances in characterizing the biology of ALS suggest that most cases of ALS are cortically-generated, part of the ALS-FTD spectrum, with focal onset and spread by contiguity within the motor super-network. Evidence-based methods identified the most credible exogenous risk factor - smoking. AB Hill's nine viewpoints to inferring causation from association were invoked. The most likely mechanism consistent with smoking being a risk factor for ALS was inferred: cumulative DNA damage, akin to cumulative somatic mutations in carcinogenesis. Focal onset supports the concept that these changes, occurring in a single cell, may trigger the cascade leading to clinical ALS. The plausibility of this mechanism was affirmed by its coherence/consistency with other observations in sporadic, familial and western Pacific ALS. Application of traditional epidemiological reasoning suggests that cumulative DNA damage may contribute to disease onset in ALS. Copyright © 2018 Elsevier B.V. All rights reserved.

    2016-01-01

    In today’s uncertain, fluid job market, transnational mobility has intensified. Though the concept of cultural transition is increasingly used in sport and career research, insight into the processes of how individuals produce their own development through work and relationships in shifting cultural patterns of meaning remains limited. The transnational industry of sports, in which athletes’ psychological adjustment to cultural transitions has implications for both performance and meaningful life, serves as a backdrop for this article. This study applied the life story method to interviews with 15 professional and semi-professional athletes, focusing particularly on the cultural transition aspect of their transnational athletic careers. The aims of the study were to identify the developmental tasks of cultural transitions and strategies/mechanisms through which cultural transitions were enacted. Three underlying mechanisms of the transition process that assisted athletic career adaptability were social repositioning, negotiation of cultural practices, and meaning reconstruction. Based on the data analyses, a temporal model of cultural transition is proposed. The results of this research provide professionals working in the fields of career counseling and migrant support with a content framework for enhancing migrant workers’ adaptabilities and psychological wellbeing.

    To assess the public's awareness of human papillomavirus (HPV) as a causative factor for oropharyngeal cancer. Twenty-three-item survey. Local shopping malls and Maxwell Air Force Base in 2012. Respondents were randomly chosen to participate in 23-item survey at various local shopping malls and at Maxwell Air Force Base in 2012. The χ(2) test was used in statistical analysis. The majority of respondents (n = 319) were civilians; 158 were military officer trainees (MOTs). All MOTs had a bachelor's degree or higher, while 37% of civilian respondents had a bachelor's degree or higher. Most MOTs (82%) were aware of oropharyngeal cancer, and 53% of civilians had not heard of oropharyngeal cancer (P < .0001). Most respondents (73% civilian and 91% military) were aware of the association between HPV and cervical cancer. Conversely, 75% of civilian population and 49% of MOTs were not aware of the association between HPV and oropharyngeal cancer (P < .0001). The majority of respondents (61% military and 81% civilian) did not know that both sexes were eligible for HPV vaccine (P < .0001). Most respondents were aware that HPV is a causative agent of cervical cancer. However, the majority were not aware of the association between oropharyngeal cancer and HPV. Furthermore, many respondents were not aware that HPV equally affects males and females and that the vaccine is available for both sexes. This underscores the need to educate the public on the availability of HPV vaccine and the association between HPV and oropharyngeal cancer. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

  2. Environmentalist thinking and the question of disease causation in late Spanish Philippines.

    PubMed

    Reyes, Raquel A G

    2014-10-01

    The scientific understanding of disease causation was crucial to the ways in which the Spanish colonial state addressed epidemic diseases which periodically struck nineteenth-century Philippines. Scholars have often described Spanish colonial responses in terms of ineptitude and failure, and have often glossed over the multiple and competing scientific theories that preoccupied Spanish and Filipino physicians. This article examines the work and ideas of nineteenth-century Spanish colonial and patriotic Filipino physicians regarding disease causation in the tropical environment of the Philippines. It will focus on two key developments-Spanish environmentalist thinking and the emerging fields of microscopy and bacteriology. Much like the British and French colonialists, Spaniards viewed tropical climates as insalubrious and conducive to disease, perceiving themselves as constitutionally at risk in hot places, ill-suited, exposed, and vulnerable to so-called native diseases. By the 1880s, however, young Filipino researchers, some of whom had trained in Spain and France, were undertaking new research on polluted water, malaria, and cells. Influenced by the revolutionary new discoveries being made in bacteriology, these researchers questioned prevailing environmentalist explanations and focused, for the first time, on the nature of pathogens and microbial pathogenesis in disease development and transmission. But germ theory remained an idea among many. This article argues that although late nineteenth-century studies in microscopy by Filipinos slowly began to challenge Spanish colonial ideas, different streams of thinking overlapped and no single scientific explanation came to predominate. © The Author 2013.

    2016-01-01

    OBJECTIVES: Septic pulmonary embolism is an uncommon but life-threatening disorder. However, data on patients with septic pulmonary embolism who require critical care have not been well reported. This study elucidated the clinicoradiological spectrum, causative pathogens and outcomes of septic pulmonary embolism in patients requiring critical care. METHODS: The electronic medical records of 20 patients with septic pulmonary embolism who required intensive care unit admission between January 2005 and December 2013 were reviewed. RESULTS: Multiple organ dysfunction syndrome developed in 85% of the patients, and acute respiratory failure was the most common organ failure (75%). The most common computed tomographic findings included a feeding vessel sign (90%), peripheral nodules without cavities (80%) or with cavities (65%), and peripheral wedge-shaped opacities (75%). The most common primary source of infection was liver abscess (40%), followed by pneumonia (25%). The two most frequent causative pathogens were Klebsiella pneumoniae (50%) and Staphylococcus aureus (35%). Compared with survivors, nonsurvivors had significantly higher serum creatinine, arterial partial pressure of carbon dioxide, and Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores, and they were significantly more likely to have acute kidney injury, disseminated intravascular coagulation and lung abscesses. The in-hospital mortality rate was 30%. Pneumonia was the most common cause of death, followed by liver abscess. CONCLUSIONS: Patients with septic pulmonary embolism who require critical care, especially those with pneumonia and liver abscess, are associated with high mortality. Early diagnosis, appropriate antibiotic therapy, surgical intervention and respiratory support are essential. PMID:27759843

    Stressful life events are known to contribute to development of depression; however, it is possible this link is bidirectional. The present study examined whether such stress generation effects are greater than the effects of stressful life events on depression, and whether stress generation is also evident with anxiety. Participants were two large age cohorts (N = 732 aged 44 years; N = 705 aged 63 years) from the West of Scotland Twenty-07 study. Stressful life events, depression, and anxiety symptoms were measured twice five years apart. Cross-lagged panel analysis examined the mutual influences of stressful life events on depression and on anxiety over time. Life events predicted later depressive symptomatology (p = .01), but the depression predicting life events relationship was less strong (p = .06), whereas earlier anxiety predicted life events five years later (p = .001). There was evidence of sex differences in the extent to which life events predicted later anxiety. This study provides evidence of stress causation for depression and weaker evidence for stress generation. In contrast, there was strong evidence of stress generation for anxiety but weaker evidence for stress causation, and that differed for men and women.

    We document differences in human-capital deployment between diversified and focused firms. We find that diversified firms have higher labor productivity and that they redeploy labor to industries with better prospects in response to changing opportunities. The opportunities and incentives provided in internal labor markets in turn affect the development of workers' human capital. We find that workers more frequently transition to other industries in which their diversified firms operate and with smaller wage losses compared with workers in the open market, even when they leave their original firms. Overall, internal labor markets provide a bright side to corporate diversification. PMID:26924889

  8. Lack of Critical Slowing Down Suggests that Financial Meltdowns Are Not Critical Transitions, yet Rising Variability Could Signal Systemic Risk.

    PubMed

    2016-01-01

    Complex systems inspired analysis suggests a hypothesis that financial meltdowns are abrupt critical transitions that occur when the system reaches a tipping point. Theoretical and empirical studies on climatic and ecological dynamical systems have shown that approach to tipping points is preceded by a generic phenomenon called critical slowing down, i.e. an increasingly slow response of the system to perturbations. Therefore, it has been suggested that critical slowing down may be used as an early warning signal of imminent critical transitions. Whether financial markets exhibit critical slowing down prior to meltdowns remains unclear. Here, our analysis reveals that three major US (Dow Jones Index, S&P 500 and NASDAQ) and two European markets (DAX and FTSE) did not exhibit critical slowing down prior to major financial crashes over the last century. However, all markets showed strong trends of rising variability, quantified by time series variance and spectral function at low frequencies, prior to crashes. These results suggest that financial crashes are not critical transitions that occur in the vicinity of a tipping point. Using a simple model, we argue that financial crashes are likely to be stochastic transitions which can occur even when the system is far away from the tipping point. Specifically, we show that a gradually increasing strength of stochastic perturbations may have caused to abrupt transitions in the financial markets. Broadly, our results highlight the importance of stochastically driven abrupt transitions in real world scenarios. Our study offers rising variability as a precursor of financial meltdowns albeit with a limitation that they may signal false alarms.

    Complex systems inspired analysis suggests a hypothesis that financial meltdowns are abrupt critical transitions that occur when the system reaches a tipping point. Theoretical and empirical studies on climatic and ecological dynamical systems have shown that approach to tipping points is preceded by a generic phenomenon called critical slowing down, i.e. an increasingly slow response of the system to perturbations. Therefore, it has been suggested that critical slowing down may be used as an early warning signal of imminent critical transitions. Whether financial markets exhibit critical slowing down prior to meltdowns remains unclear. Here, our analysis reveals that three major US (Dow Jones Index, S&P 500 and NASDAQ) and two European markets (DAX and FTSE) did not exhibit critical slowing down prior to major financial crashes over the last century. However, all markets showed strong trends of rising variability, quantified by time series variance and spectral function at low frequencies, prior to crashes.

    Pediatric cataracts are observed in 1–15 per 10,000 births with 10–25% of cases attributed to genetic causes; autosomal dominant inheritance is the most commonly observed pattern. Since the specific cataract phenotype is not sufficient to predict which gene is mutated, whole exome sequencing (WES) was utilized to concurrently screen all known cataract genes and to examine novel candidate factors for a disease-causing mutation in probands from 23 pedigrees affected with familial dominant cataract. Review of WES data for 36 known cataract genes identified causative mutations in nine pedigrees (39%) in CRYAA, CRYBB1, CRYBB3, CRYGC (2), CRYGD, GJA8 (2), and MIP and an additional likely causative mutation in EYA1; the CRYBB3 mutation represents the first dominant allele in this gene and demonstrates incomplete penetrance. Examination of crystallin genes not yet linked to human disease identified a novel cataract gene, CRYBA2, a member of the βγ-crystallin superfamily. The p.(Val50Met) mutation in CRYBA2 cosegregated with disease phenotype in a four-generation pedigree with autosomal dominant congenital cataracts with incomplete penetrance. Expression studies detected cryba2 transcripts during early lens development in zebrafish, supporting its role in congenital disease. Our data highlight the extreme genetic heterogeneity of dominant cataract as the eleven causative/likely causative mutations affected nine different genes and the majority of mutant alleles were novel. Furthermore, these data suggest that less than half of dominant cataract can be explained by mutations in currently known genes. PMID:23508780

    Burkholderia mallei and Burkholderia pseudomallei are the causative micro-organisms of Glanders and Melioidosis, respectively. Although now rare in Western countries, both micro-organisms have recently gained much interest because of their unique potential as bioterrorism agents. This paper reviews the epidemiology, pathogenesis, diagnosis and treatment of Melioidosis and Glanders. Recent patents relating to these micro-organisms, especially potential vaccines, are presented. Continued research and development is urgently needed, especially in regard to rapid and accurate diagnosis of melioidosis and glanders, efficacious therapy and primary and secondary prevention.

    Background and objectives Peritonitis before peritoneal dialysis (PD) training (pretraining peritonitis [PTP]) is an uncommon event. The study aim was to examine the causative organisms, clinical outcomes, risk factors, and long-term consequences of PTP. Design, setting, participants, & measurements In this single–center, retrospective, observational study involving all incident patients on PD who developed PTP between 1998 and 2012, we examined the causative organisms, primary response rate, complete cure rate, risk factors, and associations of PTP with peritoneal equilibration test (PET) and patient survival. For each patient in the PTP group, the patients who underwent catheter insertion immediately before and after the index case were identified as controls. Results Among 1252 incident patients on PD, 52 (4.2%) patients developed PTP, and 104 patients were identified as controls. The two groups were similar in age, sex distribution, comorbidities, and residual renal function, but the PTP group had significantly lower hemoglobin and serum albumin. Patients were followed up for a median of 37.5 months (interquartile range [IQR], 16.3–62.2 months). The most common causative organisms of PTP were Staphylococcus aureus (30.8%) and polymicrobial (21.2%); 25% had negative growth. The primary response and complete cure rates were 82.7% and 78.8%, respectively. In the PTP group, 7.7% of patients died, 9.6% of patients required catheter removal, and PD training was significantly delayed (median =42.0; IQR, 26.0–65.8 days versus 27.5; IQR, 23.0–35.0 days; P=0.01). Multivariate logistic regression analysis showed that serum albumin was the only predictor of PTP (adjusted odds ratio, 0.89 per 1-g/dl increase; 95% confidence interval, 0.82 to 0.97). There were no differences in PET results and dialysis adequacy (measured around 1 month after PD training). The PTP group had significantly worse patient survival (median =41.2; IQR, 21.8–60.5 months versus 55.8; IQR

    For over a decade, the presence of trombiculid mites in some mountain areas of La Rioja (Northern Spain) and their association with seasonal human dermatitis have been recognized. This work aimed to establish the species identity of the agent causing trombiculiasis in the study area. Trombiculid larvae (chigger mites) were collected from vegetation in the Sierra Cebollera Natural Park and in Sierra La Hez during an outbreak of human trombiculiasis in 2010. Three specimens collected from a bird were also examined. Identification was made using morphological and morphometric traits based on the most recent taxonomic sources. A comparison of those mites with specimens of the same species collected throughout Europe was performed by means of cluster analysis with multiscale bootstrap resampling and calculation of approximately unbiased p-values. All collected mites were identified as Neotrombicula inopinata (Oudemans, 1909). Therefore, this species is the most likely causative agent of trombiculiasis in Spain, not Neotrombicula autumnalis (Shaw, 1790), as it was generally assumed. No chigger was identified as N. autumnalis in the study area. Neotrombicula inopinata clearly differs from N. autumnalis in the presence of eight or more setae in the 1st and 2nd rows of dorsal idiosomal setae vs. six setae in N. autumnalis. Comparison of N. inopinata samples from different locations shows significant geographic variability in morphometric traits. Samples from Western and Eastern Europe and the Caucasus formed three separate clusters. Since the taxonomical basis of many studies concerning N. autumnalis as a causative agent of trombiculiasis is insufficient, it is highly possible that N. inopinata may be hiding behind the common name of "harvest bug" in Europe, together with N. autumnalis.

    Feline immunodeficiency virus (FIV) is an important infection in both domestic and nondomestic cats. Although many studies have provided insight into FIV pathophysiology and immunologic responses to infection in cats, questions remain regarding the association of FIV with specific disease syndromes. For many diseases, both association and causation of disease with FIV remain to be confirmed and clarified. The use of experimental infection models is unlikely to yield answers about naturally infected domestic cats and is not feasible in nondomestic felids, many of which are endangered species. Researches might consider further study of naturally occurring disease with an emphasis on confirming which diseases have a likely association with FIV.

    Jones, Susan D; Teigen, Philip M

    2008-09-01

    Focusing on three Anglo-American outbreaks of industrial anthrax, this essay engages the question of how local circumstances influenced the transmission of scientific knowledge in the late nineteenth century. Walpole (Massachusetts), Glasgow, and Bradford (Yorkshire) served as important nodes of transnational investigation into anthrax. Knowledge about the morphology and behavior of Bacillus anthracis changed little while in transit between these nodes, even during complex debates about the nature of bacterial morphology, disease causation, and spontaneous generation. Working independently of their more famous counterparts (Robert Koch and Louis Pasteur), Anglo-American anthrax investigators used visual representations of anthrax bacilli to persuade their peers that a specific, identifiable cause produced all forms of anthrax-malignant pustule (cutaneous anthrax), intestinal anthrax, and woolsorter's disease (pneumonic anthrax). By the late 1870s, this point of view also supported what we would today call an ecological notion of the disease's origins in the interactions of people, animals, and microorganisms in the context of global commerce.

    Background and Objectives Stressful life events are known to contribute to development of depression, however, it is possible this link is bi-directional. The present study examined whether such stress generation effects are greater than the effects of stressful life events on depression, and whether stress generation is also evident with anxiety. Design Participants were two large age cohorts (N = 732 aged 44 years; N = 705 aged 63 years) from the West of Scotland Twenty-07 study. Methods Stressful life events, depression and anxiety symptoms were measured twice five years apart. Cross-lagged panel analysis examined the mutual influences of stressful life events on depression and on anxiety over time. Results Life events predicted later depressive symptomatology (p = .01), but the depression predicting life events relationship was less strong (p = .06), whereas earlier anxiety predicted life events five years later (p = .001). There was evidence of sex differences in the extent to which life events predicted later anxiety. Conclusions This study provides evidence of stress causation for depression and weaker evidence for stress generation. In contrast, there was strong evidence of stress generation for anxiety but weaker evidence for stress causation, and that differed for men and women. PMID:25572915

    Background The 2007–2009 financial crisis, and its fallout, has strongly emphasized the need to define new ways and measures to study and assess the stock market dynamics. Methodology/Principal Findings The S&P500 dynamics during 4/1999–4/2010 is investigated in terms of the index cohesive force (ICF - the balance between the stock correlations and the partial correlations after subtraction of the index contribution), and the Eigenvalue entropy of the stock correlation matrices. We found a rapid market transition at the end of 2001 from a flexible state of low ICF into a stiff (nonflexible) state of high ICF that is prone to market systemic collapses. The stiff state is also marked by strong effect of the market index on the stock-stock correlations as well as bursts of high stock correlations reminiscence of epileptic brain activity. Conclusions/Significance The market dynamical states, stability and transition between economic states was studies using new quantitative measures. Doing so shed new light on the origin and nature of the current crisis. The new approach is likely to be applicable to other classes of complex systems from gene networks to the human brain.

  6. Causation and the origin of life. Metabolism or replication first?

    PubMed

    Pross, Addy

    2004-06-01

    The conceptual gulf that separates the 'metabolism first' and 'replication first' mechanisms for the emergence of life continues to cloud the origin of life debate. In the present paper we analyze this aspect of the origin of life problem and offer arguments in favor of the 'replication first' school. Utilizing Wicken's two-tier approach to causation we argue that a causal connection between replication and metabolism can only be demonstrated if replication would have preceded metabolism. In conjunction with existing empirical evidence and theoretical reasoning, our analysis concludes that there is no substantive evidence for a 'metabolism first' mechanism for life's emergence, while a coherent case can be made for the 'replication first' group of mechanisms. The analysis reaffirms our conviction that life is an extreme expression of kinetic control, and that the emergence of metabolic pathways can be understood by considering life as a manifestation of 'replicative chemistry'.

    This commentary sketches out the politics of the expansion of affordable, fast-moving nutraceutical products into rural India, with a focus on fortified foods and beverages. It examines the relationships between industry, government and humanitarian organisations that are being forged alongside the development of markets for nutraceuticals; the production of evidence and the harnessing of science to support nutraceutical companies' claims; the ways in which nutraceuticals are being marketed and distributed in rural areas; and the concepts of health and well-being that are being promulgated through those marketing campaigns. Lastly, it asks what kinds of impact fast-moving nutraceuticals are likely to have on the lives of India's rural poor. It concludes by questioning how smooth a transition to nutraceutical consumption Big Food marketing strategies can really facilitate and how readily low-income families seeking to feed their families and safeguard health will actually adopt concepts of wellness and internalise micro-nutrient associated risks.

    A multi-asset artificial stock market is developed. In the market, stocks are assigned to a number of sectors and traded by heterogeneous investors. The mechanism of continuous double auction is employed to clear order book and form daily closed prices. Simulation results of prices at the sector level show an intra-sector similarity and inter-sector distinctiveness, and returns of individual stocks have stylized facts that are ubiquitous in the real-world stock market. We find that the market risk factor has critical impact on both network topology transition and connection formation, and that sector risk factors account for the formation of intra-sector links and sector-based local interaction. In addition, the number of community in threshold-based networks is correlated negatively and positively with the value of correlation coefficients and the ratio of intra-sector links, which are respectively determined by intensity of sector risk factors and the number of sectors.

    . The main methodological limitation is that the approach does not attempt to assert a direction of causation between mental health conditions and the labor market outcomes. Unobserved heterogeneity and endogeneity are both possible and likely to some degree. Other limitations pertain to the data, which are cross-sectional and exclude some relatively rare disorders (e.g., schizophrenia). The results may have significant implications for access to appropriate treatment, which may vary greatly by psychiatric disorder profile and by gender. In the United States, private third-party coverage for treatment is obtained either directly through working full-time at a medium to large firm or through a spouse being employed. The findings thus suggest that mental health policy may need to account for labor market policy. Additional research is needed to disentangle the findings presented. For example, it is important to separate the influence of substance use disorders from mood disorder and uncover the pathways by which the different conditions in substance use disorders may influence the job market.

  12. Causative impact of air pollution on evapotranspiration in the North China Plain.

    PubMed

    Yao, Ling

    2017-10-01

    Atmospheric dispersion conditions strongly impact air pollution under identical surface emissions. The degree of air pollution in the Jing-Jin-Ji region is so severe that it may impose feedback on local climate. Reference evapotranspiration (ET 0 ) plays a significant role in the estimation of crop water requirements, as well as in studies on climate variation and change. Since the traditional correlation analysis cannot capture the causality, we apply the convergent cross mapping method (CCM) in this study to observationally investigate whether the air pollution impacts ET 0 . The results indicate that southwest regions of Jing-Jin-Ji always suffer higher PM 2.5 concentration than north regions through the whole year, and correlation analysis suggests that PM 2.5 concentration has a significant negative effect on ET 0 in most cities. The causality detection with CCM quantitatively demonstrates the significantly causative influence of PM 2.5 concentration on ET 0 , higher PM 2.5 concentration decreasing ET 0 . However, CCM analysis suggests that PM 2.5 concentration has a relatively weak causal influence on ET 0 while the correlation analysis gives the near zero correlation coefficient in Zhangjiakou city, indicating that the causative influence of PM 2.5 concentration on ET 0 is better revealed with CCM method than the correlation analysis. Considering that ET 0 is strongly associated with crop water requirement, the amount of water for agricultural irrigation could be reduced at high PM 2.5 concentrations. These findings can be utilized to improve the efficiency of water resources utilization, and reduce the exploiting amount of groundwater in the Jing-Jin-Ji region, although PM 2.5 is detrimental to human health.

    In Kaduna State of Nigeria, the high influx of people from neighboring states with eligible children for polio vaccination represents a significant proportion of the target population. Many of these children are often missed by the vaccination team. The purpose of the study was to determine the contribution of targeted stakeholders in transit polio vaccination. We used the trends of vaccinated children at transit points, motor parks and markets, well as total children vaccinated by transit teams in Chikun, Igabi and Sabon Gari Local Government Areas (LGAs) of Kaduna State, Nigeria, four rounds before and after the introduction of transit polio vaccination with targeted stakeholders in Kaduna State. A total of 87,502 under-5 children were vaccinated by the various transit teams in the three LGAs, which accounted for 3.2% of the total 2,781,162 children vaccinated by the three LGAs. For transit point vaccination, the number of vaccinated children increased from 1026 to 19,289 (302%), while motor park vaccination increased from 1289 to 4106 (318%) and market vaccination increased from 10,488 to 14,511 (138%), four rounds after the introduction of transit polio vaccination with targeted stakeholders. Engagement of targeted stakeholders significantly enhanced transit polio vaccination in Kaduna State, Nigeria. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

  14. Buying on margin, selling short in an agent-based market model

    Zhang, Ting; Li, Honggang

    2013-09-01

    Credit trading, or leverage trading, which includes buying on margin and selling short, plays an important role in financial markets, where agents tend to increase their leverages for increased profits. This paper presents an agent-based asset market model to study the effect of the permissive leverage level on traders’ wealth and overall market indicators. In this model, heterogeneous agents can assume fundamental value-converging expectations or trend-persistence expectations, and their effective demands of assets depend both on demand willingness and wealth constraints, where leverage can relieve the wealth constraints to some extent. The asset market price is determined by a market maker, who watches the market excess demand, and is influenced by noise factors. By simulations, we examine market results for different leverage ratios. At the individual level, we focus on how the leverage ratio influences agents’ wealth accumulation. At the market level, we focus on how the leverage ratio influences changes in the asset price, volatility, and trading volume. Qualitatively, our model provides some meaningful results supported by empirical facts. More importantly, we find a continuous phase transition as we increase the leverage threshold, which may provide a further prospective of credit trading.

    The unprecedented access offered by the World Wide Web brings with it the potential to gather huge amounts of data on human activities. Here we exploit this by using a toy model of financial markets, the Minority Game (MG), to investigate human speculative trading behaviour and information capacity. Hundreds of individuals have played a total of tens of thousands of game turns against computer-controlled agents in the Web-based Interactive Minority Game. The analytical understanding of the MG permits fine-tuning of the market situations encountered, allowing for investigation of human behaviour in a variety of controlled environments. In particular, our results indicate a transition in players’ decision-making, as the markets become more difficult, between deductive behaviour making use of short-term trends in the market, and highly repetitive behaviour that ignores entirely the market history, yet outperforms random decision-making.

    2015-11-01

    Plant allergens, being one of the most widespread allergenic substances, are hard to avoid. Hence, their identification and characterization are of prime importance for the diagnosis and treatment of food allergy. The reported allergies to fruits mainly evoke oral allergy syndrome caused by the presence of cross-reactive IgE to certain pollens and thus, allergy to fruits has also been linked to particular pollens. Many fruit allergies are being studied for their causative allergens, and are being characterized. Some tropical or exotic fruits are responsible for region-specific allergies for which only limited information is available, and generally lack allergen characterization. From a survey of the literature on fruit allergy, it is clear that some common fruits (apple, peach, musk melon, kiwi fruit, cherry, grape, strawberry, banana, custard apple, mango and pomegranate) and their allergens appear to be at the center of current research on food allergy. The present review focuses on common fruits reported as allergenic and their identified allergens; a brief description of allergens from six rare/tropical fruits is also covered.

  17. Transitional Flow in an Arteriovenous Fistula: Effect of Wall Distensibility

    2012-11-01

    Arteriovenous fistulae are created surgically to provide adequate access for dialysis in patients with end-stage renal disease. Transitional flow and the subsequent pressure and shear stress fluctuations are thought to be causative in the fistula failure. Since 50% of fistulae require surgical intervention before year one, understanding the altered hemodynamic stresses is an important step toward improving clinical outcomes. We perform numerical simulations of a patient-specific model of a functioning fistula reconstructed from 3D ultrasound scans. Rigid wall simulations and fluid-structure interaction simulations using an in-house finite element solver for the wall deformations were performed and compared. In both the rigid and distensible wall cases, transitional flow is computed in fistula as evidenced by aperiodic high frequency velocity and pressure fluctuations. The spectrum of the fluctuations is much more narrow-banded in the distensible case, however, suggesting a partial stabilizing effect by the vessel elasticity. As a result, the distensible wall simulations predict shear stresses that are systematically 10-30% lower than the rigid cases. We propose a possible mechanism for stabilization involving the phase lag in the fluid work needed to deform the vessel wall. Support from an NIDDK R21 - DK08-1823.

  4. Comments on the Causation of Malignant Mesothelioma: Rebutting the False Concept That Recent Exposures to Asbestos Do Not Contribute to Causation of Mesothelioma.

    PubMed

    Landrigan, Phillip J

    2016-01-01

    European asbestos manufacturers and their expert witnesses have advanced the claim that recent exposures to asbestos are not of significance in the causation of malignant mesothelioma. They argue that in cases of prolonged exposure to asbestos only the earliest exposures contribute to mesothelioma induction. The Collegium Ramazzini examined this claim and compared it with the findings of the Epidemiology and Public Health Working Group of the Second Italian Consensus Conference on Pleural Mesothelioma. This independent Working Group noted that earlier exposures are more effective in inducing mesothelioma, but that subsequent exposures also contribute and cannot be excluded. They found convincing evidence to support the conclusion that mesothelioma incidence is proportional to cumulative asbestos exposure. The Collegium Ramazzini concludes that risk of malignant mesothelioma is proportional to cumulative exposure to asbestos in which all exposures - early as well as late - contribute to the totality of risk. The Collegium Ramazzini rejects as false and scientifically unfounded the notion that only the earliest exposures to asbestos contribute to mesothelioma induction. Copyright © 2016 The Author.

  5. Economic transition and health transition: comparing China and Russia.

    1998-05-01

    Drawing on experiences from China and Russia (the world's two largest transitional economies), this paper empirically examines the impact of economic reforms on health status. While China's overall health status continued to improve after the economic reform, Russia experienced a serious deterioration in its population health. The observed differences in health performance between China and Russia can be explained by the different impacts of economic reforms on three major socioeconomic determinants of health. Depending on whether or not the reform improves physical environment (as reflected in income level and nutritional status), social environment (including social stability and security system), and health care, we would observe either a positive or a negative net effect on health. Despite remarkable differences in overall health development, China and Russia share some common problems. Mental and social health problems such as suicides and alcohol poisoning have been on the rise in both countries. These problems were much more serious in Russia, where political and social instability was more pronounced, associated with Russia's relatively radical reform process. With their economies moving toward a free market system, health sectors in China and Russia are undergoing marketization, which has had serious detrimental effect on the public health services.

  6. The End of a 60-year Riddle: Identification and Genomic Characterization of an Iridovirus, the Causative Agent of White Fat Cell Disease in Zooplankton

    The planktonic freshwater crustacean of the genus Daphnia are a model system for biomedical research and, in particular, invertebrate-parasite interactions. Up until now, no virus has been characterized for this system. Here we report the discovery of an iridovirus as the causative agent of White Fat Cell Disease (WFCD) in Daphnia. WFCD is a highly virulent disease of Daphnia that can easily be cultured under laboratory conditions. Although it has been studied from sites across Eurasia for more than 60 years, its causative agent had not been described, nor had an iridovirus been connected to WFCD before now. Here we find that an iridovirus—the Daphnia iridescent virus 1 (DIV-1)—is the causative agent of WFCD. DIV-1 has a genome sequence of about 288 kbp, with 39% G+C content and encodes 367 predicted open reading frames. DIV-1 clusters together with other invertebrate iridoviruses but has by far the largest genome among all sequenced iridoviruses. Comparative genomics reveal that DIV-1 has apparently recently lost a substantial number of unique genes but has also gained genes by horizontal gene transfer from its crustacean host. DIV-1 represents the first invertebrate iridovirus that encodes proteins to purportedly cap RNA, and it contains unique genes for a DnaJ-like protein, a membrane glycoprotein and protein of the immunoglobulin superfamily, which may mediate host–pathogen interactions and pathogenicity. Our findings end a 60-year search for the causative agent of WFCD and add to our knowledge of iridovirus genomics and invertebrate–virus interactions. PMID:29487186

  7. Young adults: vulnerable new targets of tobacco marketing.

    PubMed

    Biener, Lois; Albers, Alison B

    2004-02-01

    We examined young adult smoking patterns and receptivity to cigarette advertising to assess vulnerability to tobacco marketing strategies. We obtained data from a telephone survey of 12,072 Massachusetts adults. Smokers aged 18 to 30 years were more likely than older adults to smoke only occasionally and to consume fewer than 10 cigarettes per day. They also were more receptive to cigarette marketing and were more likely to be frequent patrons of bars and clubs. Many young adult smokers are in the initiation phase of smoking and are likely to undergo a transition to either nonsmoking or heavier smoking. If unimpeded by regulation, tobacco promotion in bars and clubs is likely to lead to increased adult smoking prevalence.

    Since the first published reports of the detection of the extra-solar planet transit of HD 209458 (Henry, et al. 2000, ApJ, 529, L41; Charbonneau, et al. 2000, ApJ, 529, L45), we have been attempting to detect and measure the transits with high enough accuracy for useful data analysis of the light curves. Our goal is to improve our observational and data analysis techniques, and hopefully upgrade our equipment, until we are able to reliably acquire milli-magnitude multiband photometry of HD 209458 both on and off transit. We believe our observatory can fill a useful niche in the long term monitoring of HD 209458 and other such planet-transit stars that will surely be discovered in the future. There is also an important astronomy education component to our project as well. The chance for our undergraduate Physics majors to participate in important publishable research can be a great motivating factor for them to continue their academic careers into graduate school. Furthermore, the fact that they have participated in such a project makes our graduates more "marketable" to the graduate schools. We also have a high school teacher and student currently participating in our project. This shows the project is useful in providing astronomy outreach beyond our local institution. We report here on our first detection of the planet-transit during the night of August 15-16, 2000 and also present our data from a series of transits during the month of October, 2000. Finally, we will present the project's current status at the time of the meeting.

  9. Altered brain-gut axis in autism: comorbidity or causative mechanisms?

    2014-10-01

    The concept that alterated communications between the gut microbiome and the brain may play an important role in human brain disorders has recently received considerable attention. This is the result of provocative preclinical and some clinical evidence supporting early hypotheses about such communication in health and disease. Gastrointestinal symptoms are a common comorbidity in patients with autism spectrum disorders (ASD), even though the underlying mechanisms are largely unknown. In addition, alteration in the composition and metabolic products of the gut microbiome has long been implicated as a possible causative mechanism contributing to ASD pathophysiology, and this hypothesis has been supported by several recently published evidence from rodent models of autism induced by prenatal insults to the mother. Recent evidence in one such model involving maternal infection, that is characterized by alterations in behavior, gut physiology, microbial composition, and related metabolite profile, suggests a possible benefit of probiotic treatment on several of the observed abnormal behaviors. © 2014 WILEY Periodicals, Inc.

    An essential step in investigating the bacterial role in the occurrence of diseases in Kappaphycus alvarezii is the characterization of bacteria associated with this seaweed. A molecular characterization was conducted on the genetic diversity of the causative agents of ice-ice disease associated with K. alvarezii widely known as the main source of kappa carrageenan. K. alvrezii infected with ice-ice were collected from the Karimunjawa island, North Java Sea, Indonesia. Using Zobell 2216E marine agar medium, nine bacterial species were isolated from the infected seaweed. The molecular characterizations revealed that the isolated bacteria causing ice-ice disease were closely related to the genera of Alteromonas, Bacillus, Pseudomonas, Pseudoalteromonas, Glaciecola, Aurantimonas, and Rhodococcus. In order to identify the symptoms causative organisms, the isolated bacterial species were cultured and were evaluated for their pathogenity. Out of 9 species, only 3 isolates were able to cause the ice-ice symptoms and consisted of Alteromonas macleodii, Pseudoalteromonas issachenkonii and Aurantimonas coralicida. A. macleodii showed the highest pathogenity.

    Konzo and lathyrism are associated with consumption of cassava and grass pea, respectively. Cassava consumption has also been associated with a third disease, tropical ataxic neuropathy (TAN). This review presents a new unifying hypothesis on the causative agents for these diseases: namely, that they are nitriles, compounds containing cyano groups. The diseases may be caused by different but similar nitriles through direct neurotoxic actions not mediated by systemic cyanide release. Both cassava and Lathyrus contain nitriles, and other unidentified nitriles can be generated during food processing or in the human body. Available data indicate that several small nitriles cause a variety of neurotoxic effects. In experimental animals, 3,3'-iminodipropionitrile (IDPN), allylnitrile and cis-crotononitrile cause sensory toxicity, whereas hexadienenitrile and trans-crotononitrile induce selective neuronal degeneration in discrete brain regions. IDPN also induces a neurofilamentous axonopathy, and dimethylaminopropionitrile is known to cause autonomic (genito-urinary) neurotoxicity in both humans and rodents. Some of these actions depend on metabolic bioactivation of the parental nitriles, and sex- and species-dependent differences in susceptibility have been recorded. Recently, neuronal degeneration has been found in rats exposed to acetone cyanohydrin. Taken together, the neurotoxic properties of nitriles make them excellent candidates as causative agents for konzo, lathyrism and TAN. Copyright © 2010 Elsevier Ltd. All rights reserved.

  13. How Have Health Insurers Performed Financially Under the ACA' Market Rules?

    PubMed

    McCue, Michael J; Hall, Mark A

    2017-10-01

    The Affordable Care Act (ACA) transformed the market for individual health insurance, so it is not surprising that insurers' transition was not entirely smooth. Insurers, with no previous experience under these market conditions, were uncertain how to price their products. As a result, they incurred significant losses. Based on this experience, some insurers have decided to leave the ACA’s subsidized market, although others appear to be thriving. Examine the financial performance of health insurers selling through the ACA's marketplace exchanges in 2015--the market’s most difficult year to date. Analysis of financial data for 2015 reported by insurers from 48 states and D.C. to the Centers for Medicare and Medicaid Services. Although health insurers were profitable across all lines of business, they suffered a 10 percent loss in 2015 on their health plans sold through the ACA's exchanges. The top quarter of the ACA exchange market was comfortably profitable, while the bottom quarter did much worse than the ACA market average. This indicates that some insurers were able to adapt to the ACA's new market rules much better than others, suggesting the ACA's new market structure is sustainable, if supported properly by administrative policy.

    Congenital hyperinsulinism of infancy (CHI) is a rare disorder characterized by severe hypoglycemia due to inappropriate insulin secretion. The genetic causes of CHI have been found in genes regulating insulin secretion from pancreatic β-cells; recessive inactivating mutations in the ABCC8 and KCNJ11 genes represent the most common events. Despite the advances in understanding the molecular pathogenesis of CHI, specific genetic determinants in about 50 % of the CHI patients remain unknown, suggesting additional locus heterogeneity. In order to search for novel loci contributing to the pathogenesis of CHI, we combined a family-based association study, using the transmission disequilibrium test on 17 CHI patients lacking mutations in ABCC8/KCNJ11, with a whole-exome sequencing analysis performed on 10 probands. This strategy allowed the identification of the potential causative mutations in genes implicated in the regulation of insulin secretion such as transmembrane proteins (CACNA1A, KCNH6, KCNJ10, NOTCH2, RYR3, SCN8A, TRPV3, TRPC5), cytosolic (ACACB, CAMK2D, CDKAL1, GNAS, NOS2, PDE4C, PIK3R3) and mitochondrial enzymes (PC, SLC24A6), and in four genes (CSMD1, SLC37A3, SULF1, TLL1) suggested by TDT family-based association study. Moreover, the exome-sequencing approach resulted to be an efficient diagnostic tool for CHI, allowing the identification of mutations in three causative CHI genes (ABCC8, GLUD1, and HNF1A) in four out of 10 patients. Overall, the present study should be considered as a starting point to design further investigations: our results might indeed contribute to meta-analysis studies, aimed at the identification/confirmation of novel causative or modifier genes.

    2012-01-01

    Within a study of accident data from GIDAS (German In-Depth Accident Study), vulnerable road users are investigated regarding injury risk in traffic accidents. GIDAS is the largest in-depth accident study in Germany. Due to a well-defined sampling plan, representativeness with respect to the federal statistics is also guaranteed. A hierarchical system ACASS (Accident Causation Analysis with Seven Steps) was developed in GIDAS, describing the human causation factors in a chronological sequence. The accordingly classified causation factors - derived from the systematic of the analysis of human accident causes ("7 steps") - can be used to describe the influence of accident causes on the injury outcome. The bases of the study are accident documentations over ten years from 1999 to 2008 with 8204 vulnerable road users (VRU), of which 3 different groups were selected as pedestrians n=2041, motorcyclists n=2199 and bicyclists n=3964, and analyzed on collisions with cars and trucks as well as vulnerable road users alone. The paper will give a description of the injury pattern and injury mechanisms of accidents. The injury frequencies and severities are pointed out considering different types of VRU and protective measures of helmet and clothes of the human body. The impact points are demonstrated on the car, following to conclusion of protective measures on the vehicle. Existing standards of protection devices as well as interdisciplinary research, including accident and injury statistics, are described. With this paper, a summarization of the existing possibilities on protective measures for pedestrians, bicyclists and motorcyclists is given and discussed by comparison of all three groups of vulnerable road users. Also the relevance of special impact situations and accident causes mainly responsible for severe injuries are pointed out, given the new orientation of research for the avoidance and reduction of accident patterns. 2010 Elsevier Ltd.

    We use register data of 88,948 sick-listed workers in Denmark over the period 2008-2011 to investigate the effect of active labor market programs on the duration until returning to non-subsidized employment and the duration of this employment. To identify causal treatment effects, we exploit over-time variation in the use of active labor market programs in 98 job centers and time-to- event. We find that ordinary education and subsidized job training have significant positive employment effects. Subsidized job training has a large, positive effect on the transition into employment but no effect on the subsequent employment duration. In contrast, ordinary education has a positive effect on employment duration but no effect on the transition into employment. The latter effect is the result of two opposing effects, a large positive effect of having completed education and a large negative lock-in effect, with low re-employment chances during program participation.

    Exposure of guinea pigs to x rays of 400 r after active immunization with the toxoids of the causative organisms of gas-gangrene and tetanus led to a certain decrease in the antitoxin titre to all tyPes of antigens. The most considerable decrease in the antitoxin titre after irradiation was found in the sera of animals immunized with Cl.perfringens toxoid. The antitoxin titre decreased already after one day to 1/6th of the titre found in animals not exposed to radiation, The smallest decrease in antitoxin tltre was found in animals immunized with tetanus toxoid. Prolongation of the period elapsed after themore » radiation to 5 days did not reveal a further decrease in the antitoxin titres found in the sera of the immunized animals. A certain discrepancy was observed between the antitoxin titre of immunized animals exposed to radiation and their resistance to infection with the corresponding bacterial species: notwithstanding the high antitoxin tltre, the immunity after irradiation proved to be completely suppressed. The susceptibility of immunized animals to the causative organisms of gas-gangrene and tetanus decreased considerably after exposure to radiation and approached the susceptibillty of unimmunized animals, (auth)« less

    This commentary sketches out the politics of the expansion of affordable, fast-moving nutraceutical products into rural India, with a focus on fortified foods and beverages. It examines the relationships between industry, government and humanitarian organisations that are being forged alongside the development of markets for nutraceuticals; the production of evidence and the harnessing of science to support nutraceutical companies’ claims; the ways in which nutraceuticals are being marketed and distributed in rural areas; and the concepts of health and well-being that are being promulgated through those marketing campaigns. Lastly, it asks what kinds of impact fast-moving nutraceuticals are likely to have on the lives of India’s rural poor. It concludes by questioning how smooth a transition to nutraceutical consumption Big Food marketing strategies can really facilitate and how readily low-income families seeking to feed their families and safeguard health will actually adopt concepts of wellness and internalise micro-nutrient associated risks.

  1. Consistent Treatment of Variables and Causation Poses a Challenge for Behavioral Research Methods: A Commentary on Nesselroade and Molenaar (2016).

    PubMed

    Markus, Keith A

    2016-01-01

    Nesselroade and Molenaar presented the ideographic filter as a proposal for analyzing lawful regularities in behavioral research. The proposal highlights an inconsistency that poses a challenge for behavioral research more generally. One can distinguish a broadly Humean approach from a broadly non-Humean approach as they relate to variables and to causation. Nesselroade and Molenaar rejected a Humean approach to latent variables that characterizes them as nothing more than summaries of their manifest indicators. By contrast, they tacitly accepted a Humean approach to causes characterized as nothing more than summaries of their manifest causal effects. A non-Humean treatment of variables coupled with a Humean treatment of causation creates a theoretical tension within their proposal. For example, one can interpret the same model elements as simultaneously representing both variables and causes. Future refinement of the ideographic filter proposal to address this tension could follow any of a number of strategies.

  2. Correlation versus Causation? Pharmacovigilance of the Analgesic Flupirtine Exemplifies the Need for Refined Spontaneous ADR Reporting

    PubMed Central

    Anderson, Nora; Borlak, Juergen

    2011-01-01

    Annually, adverse drug reactions result in more than 2,000,000 hospitalizations and rank among the top 10 causes of death in the United States. Consequently, there is a need to continuously monitor and to improve the safety assessment of marketed drugs. Nonetheless, pharmacovigilance practice frequently lacks causality assessment. Here, we report the case of flupirtine, a centrally acting non-opioid analgesic. We re-evaluated the plausibility and causality of 226 unselected, spontaneously reported hepatobiliary adverse drug reactions according to the adapted Bradford-Hill criteria, CIOMS score and WHO-UMC scales. Thorough re-evaluation showed that only about 20% of the reported cases were probable or likely for flupirtine treatment, suggesting an incidence of flupirtine-related liver injury of 1∶ 100,000 when estimated prescription data are considered, or 0.8 in 10,000 on the basis of all 226 reported adverse drug reactions. Neither daily or cumulative dose nor duration of treatment correlated with markers of liver injury. In the majority of cases (151/226), an average of 3 co-medications with drugs known for their liver liability was observed that may well be causative for adverse drug reactions, but were reported under a suspected flupirtine ADR. Our study highlights the need to improve the quality and standards of ADR reporting. This should be done with utmost care taking into account contributing factors such as concomitant medications including over-the-counter drugs, the medical history and current health conditions, in order to avoid unjustified flagging and drug warnings that may erroneously cause uncertainty among healthcare professionals and patients, and may eventually lead to unjustified safety signals of useful drugs with a reasonable risk to benefit ratio.

  3. The Human Ureaplasma Species as Causative Agents of Chorioamnionitis

    2016-01-01

    SUMMARY The human Ureaplasma species are the most frequently isolated microorganisms from the amniotic fluid and placentae of women who deliver preterm and are also associated with spontaneous abortions or miscarriages, neonatal respiratory diseases, and chorioamnionitis. Despite the fact that these microorganisms have been habitually found within placentae of pregnancies with chorioamnionitis, the role of Ureaplasma species as a causative agent has not been satisfactorily explained. There is also controversy surrounding their role in disease, particularly as not all women infected with Ureaplasma spp. develop chorioamnionitis. In this review, we provide evidence that Ureaplasma spp. are associated with diseases of pregnancy and discuss recent findings which demonstrate that Ureaplasma spp. are associated with chorioamnionitis, regardless of gestational age at the time of delivery. Here, we also discuss the proposed major virulence factors of Ureaplasma spp., with a focus on the multiple-banded antigen (MBA), which may facilitate modulation/alteration of the host immune response and potentially explain why only subpopulations of infected women experience adverse pregnancy outcomes. The information presented within this review confirms that Ureaplasma spp. are not simply “innocent bystanders” in disease and highlights that these microorganisms are an often underestimated pathogen of pregnancy.

    Dormady, Noah Christopher

    Chapter 1: A Monte Carlo Approach. The use of auctions to distribute tradeable property rights to firms in already heavily concentrated markets may further exacerbate the problems of market power that exist within those markets. This chapter provides a model of a two-stage emissions market modeled after a contemporary regional permit trading market in the United States, the Regional Greenhouse Gas Initiative, Inc. (RGGI). It then introduces Oligopsony 1.0, a C# software package constructed in the .NET environment that simulates uniform-price auctions using stochastic Monte Carlo simulation for modeling market power in tradeable property rights auctions. Monte Carlo methods add a probabilistic element to standard auction theoretic equilibria. The results of these simulations indicate that there can be significant non-linearities between profit and market power as exercised through strategic demand reduction. This analysis finds the optimum point of strategic demand reduction that enables the firm to exploit these non-linearities, and it determines the probability distributions of these optima using kernel density analysis. Chapter 2: An Experimental Approach. How will emerging auction-based emissions markets function within the context of today's deregulated auction-based electricity markets? This chapter provides an experimental analysis of a joint energy-emissions market. The impact of market power and collusion among dominant firms is evaluated to determine the extent to which an auction-based tradeable permit market influences performance in an adjacent electricity market. The experimental treatment design controls for a variety of real-world institutional features, including variable demand, permit banking, inter-temporal (multi-round) dynamics, a tightening cap, and resale. Results suggest that the exercise of market power significantly increases electricity auction clearing prices, without significantly increasing emissions

    1990-01-01

    Health care has entered an era of rapid change. Most observers agree that important long-term changes will fundamentally reshape health care as we know it. To that end, health care providers should consider the benefits of operating vertically integrated marketing system with hospitals as the channel leader. Whether an administered VMS (hospitals have the power to gain compliance) or a corporate VMS (hospitals own successive levels of care providers), integrated channel management holds the promise of cost containment and quality patient care for the future. However, a great deal of integrating work must be done before VMSs will become a practical solution. Research studies are needed on each of the issues just discussed. As marketers, it is time we make a transition from treating health care marketing as a disjointed entity and instead treat it as an industry where all marketing principles are considered including channel management.

    In traditional econometrics, a time series must be in a stationary sequence. However, it usually shows time-varying fluctuations, and it remains a challenge to execute a multiscale analysis of the data and discover the topological characteristics of conduction in different scales. Wavelet analysis and complex networks in physical statistics have special advantages in solving these problems. We select the exchange rate variable from the Chinese market and the commodity price index variable from the world market as the time series of our study. We explore the driving factors behind the behavior of the two markets and their topological characteristics in three steps. First, we use the Kalman filter to find the optimal estimation of the relationship between the two markets. Second, wavelet analysis is used to extract the scales of the relationship that are driven by different frequency wavelets. Meanwhile, we search for the actual economic variables corresponding to different frequency wavelets. Finally, a complex network is used to search for the transfer characteristics of the combination of states driven by different frequency wavelets. The results show that statistical physics have a unique advantage over traditional econometrics. The Chinese market has time-varying impacts on the world market: it has greater influence when the world economy is stable and less influence in times of turmoil. The process of forming the state combination is random. Transitions between state combinations have a clustering feature. Based on these characteristics, we can effectively reduce the information burden on investors and correctly respond to the government's policy mix.

    Recently Myanmar transitioned from a closed economy, military government to market based economy and democracy. The impacts of the political and economic transition on its land cover can be described by characterizing the land cover dynamics during the transition period. Preliminary stratified sampling of forest conversions revealed that most changes from forest to non-forest are due to establishment of rubber plantations. Agricultural concessions are granted by the government to develop the agriculture sector and rubber is the most common plantation crop in Southern Myanmar. This study establishes a method to map and quantify the extent and age of rubber plantations in Thaton district of Myanmar using satellite remote sensing, GIS and ground data. The resultant rubber maps can be used to inform policy on land use planning, agriculture, forest and sustainable development.

    This work introduces automated optimization into fuel cycle simulations in the Cyclus platform. This includes system-level optimizations, seeking a deployment plan that optimizes the performance over the entire transition, and market-level optimization, seeking an optimal set of material trades at each time step. These concepts were introduced in a way that preserves the flexibility of the Cyclus fuel cycle framework, one of its most important design principles.

  9. The Price-Concentration Relationship in Early Residential Solar Third-Party Markets

    The market for residential solar photovoltaic (PV) systems in the United States has experienced tremendous growth over the past decade, with installed capacity more than doubling between 2014 and 2016 alone (SEIA, 2016). As the residential market continues to grow, it prompts new questions about the nature of competition between solar installers and how this competition, or lack thereof, affects the prices consumers are paying. It is often assumed that more competition leads to lower prices, but this is not universally true. For example, some studies have shown that factors such as brand loyalty could lead to a negative relationshipmore » between concentration and price in imperfectly competitive markets (Borenstein, 1985; Holmes, 1989). As such, the relationship between prices and market concentration is an open empirical question since theory could predict either a positive or negative relationship. Determining a relationship between prices and market concentration is challenging for several reasons. Most significantly, prices and market structure are simultaneously determined by each other -- the amount of competition a seller faces influences the price they can command, and prices determine a seller's market share. Previous studies have examined recent PV pricing trends over time and between markets (Davidson et al., 2015a; Davidson and Margolis 2015b; Nemet et al., 2016; Gillingham et al., 2014; Barbose and Darghouth 2015). While these studies of solar PV pricing are able to determine correlations between prices and market factors, they have not satisfactorily proven causation. Thus, to the best of our knowledge, there is little work to date that focuses on identifying the causal relationship between market structure and the prices paid by consumers. We use a unique dataset on third-party owned contract terms for the residential solar PV market in the San Diego Gas and Electricity service territory to better understand this relationship. Surprisingly, we

    Major economic transitions typically entail changes in the availability of and purchasing power for different types of foods leading to long-term changes in the composition of the diet. Bulgaria, a former Eastern Bloc country, underwent a difficult and protracted transition from a centralized to market economy with acute economic crises and a much slower recovery of income levels than in Poland, the Czech Republic, and Hungary. Using annual data from the Bulgarian National Household Survey, we study changes in the reported consumption of major foods (excluding alcoholic drinks) and their constituent macronutrients from 1985 to 2002, examining also the differences in dietary patterns between the period prior to and following the transition. The consumption of most major food items decreased, resulting in a fall in per capita energy consumption of 429 kcal/day (1.80 MJ/d), following the economic transition of 1991. As expected, the consumption of foods that were more expensive per unit of energy decreased greater than cheaper foods, -34% for animal products and -19% for visible fats, but only -10% for carbohydrates. These changes are related to the changes in income and market prices as well as the general negative trend in economic growth and hyperinflation in the mid-1990s. Thus, Bulgaria experienced a decrease in food consumption without significant changes in the dietary pattern following the economic transition of 1991. The fact that part of this decline may be attributed to continued economic challenges suggests that future transitions in the diet may be expected as economic development proceeds.

  11. Neotrombicula inopinata (Acari: Trombiculidae) – a possible causative agent of trombiculiasis in Europe

    PubMed Central

    2014-01-01

    Background For over a decade, the presence of trombiculid mites in some mountain areas of La Rioja (Northern Spain) and their association with seasonal human dermatitis have been recognized. This work aimed to establish the species identity of the agent causing trombiculiasis in the study area. Methods Trombiculid larvae (chigger mites) were collected from vegetation in the Sierra Cebollera Natural Park and in Sierra La Hez during an outbreak of human trombiculiasis in 2010. Three specimens collected from a bird were also examined. Identification was made using morphological and morphometric traits based on the most recent taxonomic sources. A comparison of those mites with specimens of the same species collected throughout Europe was performed by means of cluster analysis with multiscale bootstrap resampling and calculation of approximately unbiased p-values. Results All collected mites were identified as Neotrombicula inopinata (Oudemans, 1909). Therefore, this species is the most likely causative agent of trombiculiasis in Spain, not Neotrombicula autumnalis (Shaw, 1790), as it was generally assumed. No chigger was identified as N. autumnalis in the study area. Neotrombicula inopinata clearly differs from N. autumnalis in the presence of eight or more setae in the 1st and 2nd rows of dorsal idiosomal setae vs. six setae in N. autumnalis. Comparison of N. inopinata samples from different locations shows significant geographic variability in morphometric traits. Samples from Western and Eastern Europe and the Caucasus formed three separate clusters. Conclusion Since the taxonomical basis of many studies concerning N. autumnalis as a causative agent of trombiculiasis is insufficient, it is highly possible that N. inopinata may be hiding behind the common name of “harvest bug” in Europe, together with N. autumnalis.

    Researchers and conservation managers largely agree on the relevance of traditional ecological knowledge for natural resource management in indigenous communities, but its prevalence and role as societies modernize are contested. We analyzed the transmission of traditional knowledge among rural local people in communities linked to protected areas in Doñana, southwestern Spain. We studied changes in knowledge related to local practices in agriculture and livestock farming among 198 informants from three generations that cover the period in which the area transited from an economy strongly dependent on local ecosystem services to a market economy with intensified production systems. Our results suggest an abrupt loss of traditional agricultural knowledge related to rapid transformations and intensification of agricultural systems, but maintenance of knowledge of traditional livestock farming, an activity allowed in the protected areas that maintains strong links with local cultural identity. Our results demonstrate the potential of protected areas in protecting remaining bodies of traditional ecological knowledge in developed country settings. Nevertheless, we note that strict protection in cultural-landscape-dominated areas can disrupt transmission of traditional knowledge if local resource users and related practices are excluded from ecosystem management.

    The assumption in the personality and politics literature is that a person's personality motivates them to develop certain political attitudes later in life. This assumption is founded on the simple correlation between the two constructs and the observation that personality traits are genetically influenced and develop in infancy, whereas political preferences develop later in life. Work in psychology, behavioral genetics, and recently political science, however, has demonstrated that political preferences also develop in childhood and are equally influenced by genetic factors. These findings cast doubt on the assumed causal relationship between personality and politics. Here we test the causal relationship between personality traits and political attitudes using a direction of causation structural model on a genetically informative sample. The results suggest that personality traits do not cause people to develop political attitudes; rather, the correlation between the two is a function of an innate common underlying genetic factor.

    The Pacific broad tapeworm Adenocephalus pacificus (syn. Diphyllobothrium pacificum) is the causative agent of the third most common fish-borne cestodosis among humans. Although most of the nearly 1,000 cases among humans have been reported in South America (Peru, Chile, and Ecuador), cases recently imported to Europe demonstrate the potential for spread of this tapeworm throughout the world as a result of global trade of fresh or chilled marine fish and travel or migration of humans. We provide a comprehensive survey of human cases of infection with this zoonotic parasite, summarize the history of this re-emerging disease, and identify marine fish species that may serve as a source of human infection when eaten raw or undercooked.

    This article investigates the effect of family life course transitions on labor allocation strategies in rural Chinese households. We highlight three types of economic activity that involve reallocation of household labor oriented toward a more diversified, nonfarm rural economy: involvement in wage employment, household entrepreneurship, and/or multiple activities that span economic sectors. With the use of data from the China Health and Nutrition Survey (CHNS 1997, 2000, and 2004), our longitudinal analyses of rural household economic activity point to the significance of household demography, life course transitions, and local economic structures as factors facilitating household labor reallocation. First, as expected, a relatively youthful household structure is conducive to innovative economic behavior. Second, household entrances and exits are significant, but their impacts are not equal. Life events such as births, deaths, marriage, or leaving home for school or employment affect household economy in distinctive ways. Finally, the reallocations of household labor undertaken by households are shaped by local economic structures: in particular, the extent of village-level entrepreneurial activity, off-farm employment, and out-migration.

    Married adults show better psychological adjustment and physical health than their separated/divorced or never-married counterparts. However, this apparent “marriage benefit” may be due to social selection, social causation, or both processes. Genetically informed research designs offer critical advantages for helping to disentangle selection from causation by controlling for measured and unmeasured genetic and shared environmental selection. Using young-adult twin and sibling pairs from the National Longitudinal Study of Adolescent Health (Harris, 2009), we conducted genetically informed analyses of the association between entry into marriage, cohabitation, or singlehood and multiple indices of psychological and physical health. The relation between physical health and marriage was completely explained by nonrandom selection. For internalizing behaviors, selection did not fully explain the benefits of marriage or cohabitation relative to being single, whereas for externalizing symptoms, marriage predicted benefits over cohabitation. The genetically informed approach provides perhaps the strongest nonexperimental evidence that these observed effects are causal. PMID:23088795

    2018-01-01

    We show that there is a phase transition in the bounded rational Carfì-Musolino model, and the possibility of a market crash. This model has two types of operators: a real economic subject (Air) and one or more investment banks (Bank). It also has two markets: oil spot market and US dollar futures. Bank agents react to Air and equilibrate much more quickly than Air. Thus Air is an acting external agent due to its longer-term investing, whereas the action of the banks equilibrates before Air makes its next transaction. This model constitutes a potential game, and agents crowd their preferences into one of the markets at a critical temperature when air makes no purchases of oil futures.

    The changing structure of demand for commodities associated with food security and energy has had a startling impact on land use change in tropical forests in recent decades. Yet, the composition of conversion in the Congo basin remains a major uncertainty, particularly with regards to the scale of drivers of change. Owing to rapid expansion of production globally and longstanding historical production locally in the Congo basin, oil palm offers a lens through which to evaluate local land use decisions across a spectrum of small- to large-scales of production as well as interactions with regional and global supply chains. We examined the effect of global commodity crop expansion on land use change in Southwest Cameroon using a mixed-methods approach to integrate remote sensing, field surveys and socioeconomic data. Southwest Cameroon (2.5 Mha) has a long history of large- and small-scale agriculture, ranging from mixed crop subsistence agriculture to large monocrop plantations of oil palm, cocoa, and rubber. Trends and spatial patterns of forest conversion and agricultural transitions were analyzed from 2000-2015 using satellite imagery. We used economic, demographic and field survey datasets to assess how regional and global market factors and local commodity crop decisions affect land use patterns. Our results show that oil palm is a major commodity crop expanding in this region, and that conversion is occurring primarily through expansion by medium-scale producers and local elites. Results also indicate that global and regional supply chain dynamics influence local land use decision making. This research contributes new information on land use patterns and dynamics in the Congo basin, an understudied region. More specifically, results from this research contribute information on recent trends of oil palm expansion in Cameroon that will be used in national land use planning strategies.

    Internet alcohol marketing is not well studied despite its prevalence and potential accessibility and attractiveness to youth. The objective was to examine longitudinal associations between self-reported engagement with Internet alcohol marketing and alcohol use transitions in youth. A US sample of 2012 youths aged 15 to 20 was surveyed in 2011. An Internet alcohol marketing receptivity score was developed, based on number of positive responses to seeing alcohol advertising on the Internet, visiting alcohol brand Web sites, being an online alcohol brand fan, and cued recall of alcohol brand home page images. We assessed the association between baseline marketing receptivity and both ever drinking and binge drinking (≥6 drinks per occasion) at 1-year follow-up with multiple logistic regression, controlling for baseline drinking status, Internet use, sociodemographics, personality characteristics, and peer or parent drinking. At baseline, ever-drinking and binge-drinking prevalence was 55% and 27%, respectively. Many (59%) reported seeing Internet alcohol advertising, but few reported going to an alcohol Web site (6%) or being an online fan (3%). Higher Internet use, sensation seeking, having family or peers who drank, and past alcohol use were associated with Internet alcohol marketing receptivity, and a score of 1 or 2 was independently associated with greater adjusted odds of initiating binge drinking (odds ratio 1.77; 95% confidence interval, 1.13-2.78 and odds ratio 2.15; 95% confidence interval, 1.06-4.37 respectively) but not with initiation of ever drinking. Although high levels of engagement with Internet alcohol marketing were uncommon, most underage youths reported seeing it, and we found a prospective association between receptivity to this type of alcohol marketing and future problem drinking, making additional research and ongoing surveillance important.

    Systematic reviews examining associations of depressive disorder with coronary heart disease and stroke produce mixed results. Failure to consider reverse causation and dose-response patterns may have caused inconsistencies in evidence. This prospective cohort study on depressive disorder, coronary heart disease, and stroke analysed reverse causation and dose-response effects using four 5-year and three 10-year observation cycles (total follow up 24 years) based on multiple repeat measures of exposure. Participants in the Whitehall II study (n = 10,036, 31,395 person-observations, age at start 44.4 years) provided up to six repeat measures of depressive symptoms via the 30-item General Health Questionnaire (GHQ-30) and one measure via Center for Epidemiologic Studies Depression Scale (CES-D). The cohort was followed up for major coronary events (coronary death/nonfatal myocardial infarction) and stroke (stroke death/morbidity) through the national mortality register Hospital Episode Statistics, ECG-screening, medical records, and self-report questionnaires. GHQ-30 caseness predicted stroke over 0-5 years (age-, sex- and ethnicity-adjusted HR 1.60, 95% CI 1.1-2.3) but not over 5-10 years (HR 0.94, 95% CI 0.6-1.4). Using the last 5-year observation cycle, cumulative GHQ-30 caseness was associated with incident coronary heart disease in a dose-response manner (1-2 times a case: HR 1.12, 95% CI 0.7-1.7; 3-4 times: HR 2.06, 95% CI 1.2-3.7), and CES-D caseness predicted coronary heart disease (HR 1.81, 95% CI 1.1-3.1). There was evidence of a dose-response effect of depressive symptoms on risk of coronary heart disease. In contrast, prospective associations of depressive symptoms with stroke appeared to arise wholly or partly through reverse causation.

    ABSTRACT Thailand has experienced dramatic growth of large national and international modern food retailers, such as supermarkets, hypermarkets and convenience stores in large cities and regional centres in the last two decades. Nevertheless, Thai consumers continue to purchase perishables (fruits, vegetables and animal products) from fresh markets (wet markets, talat sot) contradicting predictions from analysts that modern food retail chains will rapidly replace fresh markets as the preferred venue for purchasing all types of foods. This paper examines trust in food retail systems as an under-explored dimension lying behind the continued patronage by Thais of fresh markets to purchase perishable items. It derives from a research program commenced in 2005 that includes fieldwork visits, interviews and questionnaires. In the context of the Thai food retail transition, we propose that trust affects relationships between consumers and (1) individual fresh market-based vendors, (2) the food products sold at fresh markets and (3) the food retail system more broadly. If fresh markets can be maintained in the face of sustained pressure from modern national and international food retailers, Thais will continue to use them. Meanwhile, trust is a relatively unrecognised dimension that is supporting the continued existence of traditional food retail formats. PMID:27499561

    Recently, China has frequently experienced large-scale, severe and persistent haze pollution due to surging urbanization and industrialization and a rapid growth in the number of motor vehicles and energy consumption. The vehicle emission due to the consumption of a large number of fossil fuels is no doubt a critical factor of the haze pollution. This work is focused on the causation mechanism of haze pollution related to the vehicle emission for Guangzhou city by employing the Fault Tree Analysis (FTA) method for the first time. With the establishment of the fault tree system of "Haze weather-Vehicle exhausts explosive emission", all of the important risk factors are discussed and identified by using this deductive FTA method. The qualitative and quantitative assessments of the fault tree system are carried out based on the structure, probability and critical importance degree analysis of the risk factors. The study may provide a new simple and effective tool/strategy for the causation mechanism analysis and risk management of haze pollution in China. Copyright © 2016 Elsevier Ltd.

    A simple Ising spin model which can describe the mechanism of advertising in a duopoly market is proposed. In contrast to other agent-based models, the influence does not flow inward from the surrounding neighbors to the center site, but spreads outward from the center to the neighbors. The model thus describes the spread of opinions among customers. It is shown via standard Monte Carlo simulations that very simple rules and inclusion of an external field-an advertising campaign-lead to phase transitions.

    We investigate the relative market efficiency in financial market data, using the approximate entropy(ApEn) method for a quantification of randomness in time series. We used the global foreign exchange market indices for 17 countries during two periods from 1984 to 1998 and from 1999 to 2004 in order to study the efficiency of various foreign exchange markets around the market crisis. We found that on average, the ApEn values for European and North American foreign exchange markets are larger than those for African and Asian ones except Japan. We also found that the ApEn for Asian markets increased significantly after the Asian currency crisis. Our results suggest that the markets with a larger liquidity such as European and North American foreign exchange markets have a higher market efficiency than those with a smaller liquidity such as the African and Asian markets except Japan.

  11. A neural network model of causative actions.

    PubMed

    Lee-Hand, Jeremy; Knott, Alistair

    2015-01-01

    A common idea in models of action representation is that actions are represented in terms of their perceptual effects (see e.g., Prinz, 1997; Hommel et al., 2001; Sahin et al., 2007; Umiltà et al., 2008; Hommel, 2013). In this paper we extend existing models of effect-based action representations to account for a novel distinction. Some actions bring about effects that are independent events in their own right: for instance, if John smashes a cup, he brings about the event of the cup smashing. Other actions do not bring about such effects. For instance, if John grabs a cup, this action does not cause the cup to "do" anything: a grab action has well-defined perceptual effects, but these are not registered by the perceptual system that detects independent events involving external objects in the world. In our model, effect-based actions are implemented in several distinct neural circuits, which are organized into a hierarchy based on the complexity of their associated perceptual effects. The circuit at the top of this hierarchy is responsible for actions that bring about independently perceivable events. This circuit receives input from the perceptual module that recognizes arbitrary events taking place in the world, and learns movements that reliably cause such events. We assess our model against existing experimental observations about effect-based motor representations, and make some novel experimental predictions. We also consider the possibility that the "causative actions" circuit in our model can be identified with a motor pathway reported in other work, specializing in "functional" actions on manipulable tools (Bub et al., 2008; Binkofski and Buxbaum, 2013).

    Research suggests individuals possess multifaceted cognitive representations of various diseases. These illness representations consist of various beliefs, including causal attributions for the disease, and are believed to motivate, guide, and shape health-related behavior. As little research has examined factors associated with beliefs about cancer causation, this study examined the relationship between personal and family history of cancer and beliefs about the causes and prevention of malignant disease. Data were obtained from 6369 adult respondents to the 2003 Health Information National Trends Survey, a national population-based survey. Information about personal and family history of cancer and beliefs regarding cancer causation and prevention was obtained. Results showed both a personal and family history of cancer were associated with differences in beliefs about the causes of cancer. In general, a personal history of cancer was not significantly linked to causal attributions for cancer relative to those without a personal history. In contrast, a family history of cancer tended to increase the likelihood a respondent viewed a particular cause as increasing cancer risk. Thus, personal and vicarious experience with cancer had dramatically diverging influences on attributions of cancer causation, which may be due to differing self-protection motives. Results support the belief that illness representations, in this case the causal belief component, are influenced by both personal and vicarious experience with a disease and also suggest illness representations may influence receptivity to messages and interventions designed to increase appropriate cancer risk reduction behavior.

    The paper aims at identifying and assessing the revenues and costs incurred by various modernization and modernization-development strategies for a power plant in order to optimize the electric and thermal energy are produced and to conduct a sensitivity analysis of the main performance indicators. The Romanian energy system and the energy market have gone a long transition way, from the vertically integrated model, the responsibility for the delivery of the electricity comes exclusively to a state monopoly, to a decentralized system, characterized by the decentralization of production and transport, respectively distribution activities. Romania chose the liberal market model where the relations between the actors in the market - producers and suppliers free to make sales and purchase transactions for electrical energy - are mostly governed by contracts, which may be either bilaterally negotiated or are already regulated. Therefore, the importance of understanding the development trend of the Romanian energy market lies in its economic effects upon the solutions which could be adopted for the evolution of the cogeneration power plant in question.

    To estimate the incremental cost of nosocomial bacteremia according to the causative focus and classified by the antibiotic sensitivity of the microorganism.Patients admitted to Hospital del Mar in Barcelona from 2005 to 2012 were included. We analyzed the total hospital costs of patients with nosocomial bacteremia caused by microorganisms with a high prevalence and, often, with multidrug-resistance. A control group was defined by selecting patients without bacteremia in the same diagnosis-related group.Our hospital has a cost accounting system (full-costing) that uses activity-based criteria to estimate per-patient costs. A logistic regression was fitted to estimate the probability of developing bacteremia (propensity score) and was used for propensity-score matching adjustment. This propensity score was included in an econometric model to adjust the incremental cost of patients with bacteremia with differentiation of the causative focus and antibiotic sensitivity.The mean incremental cost was estimated at &OV0556;15,526. The lowest incremental cost corresponded to bacteremia caused by multidrug-sensitive urinary infection (&OV0556;6786) and the highest to primary or unknown sources of bacteremia caused by multidrug-resistant microorganisms (&OV0556;29,186).This is one of the first analyses to include all episodes of bacteremia produced during hospital stays in a single study. The study included accurate information about the focus and antibiotic sensitivity of the causative organism and actual hospital costs. It provides information that could be useful to improve, establish, and prioritize prevention strategies for nosocomial infections.

  16. Developing health insurance in transitional Asia.

    PubMed

    Ensor, T

    1999-04-01

    Many European and Asian economies are currently undergoing a process of economic transition away from state based command systems to market led economies. The impact of transition, such as a decline in public expenditure, break up of state enterprises and economic recession, has affected levels of funding available for social sectors. In the health sector, health insurance is being introduced as a way of alleviating the decline in funding arising from these processes. Most of the Former Soviet Union and a number of other Asian transition economies are currently introducing, extending or considering payroll based systems of health insurance. Comparisons with many Latin American countries, where social security based insurance has been encouraged since the first World War, can be illuminating. Experience suggests that, various factors have impeded or permitted development in these countries. General processes of economic change (transition factors) tend to affect all economies attempting to change the basis for public funding of services. Structural factors, such as urbanisation and the level of state or industrial employment, act as longer term inhibitors to the extension of coverage. These factors vary considerably across transition economies. This suggests that while a social security base for insurance may be a viable option for smaller industrialised European transitional economies, this is not the case for many of larger less industrialised economies. It is unclear how insurance will develop in the future. If a separate insurance fund is maintained it is important that its' purchasing function is developed. Otherwise it is not clear what value is added to the current health system. If entitlement is to be based on contribution, with the fund based on geographic or employment groups, systems for ensuring access for those not in employment and not classified as socially protected must be developed.

  17. Shift work, cancer and "white-box" epidemiology: Association and causation.

    PubMed

    Erren, Thomas C

    2010-11-30

    This commentary intends to instigate discussions about upcoming epidemiologic research, and its interpretation, into putative links between shift work, involving circadian disruption or chronodisruption [CD], and the development of internal cancers.In 2007, the International Agency for Research on Cancer (IARC) convened an expert group to examine the carcinogenicity of shift work, inter alia characterized by light exposures at unusual times. After a critical review of published data, the following was stated: "There is sufficient evidence in experimental animals for the carcinogenicity of light during the daily dark period (biological night)". However, in view of limited epidemiological evidence, it was overall concluded: "Shiftwork that involves circadian disruption is probably carcinogenic to humans (Group 2A)".Remarkably, the scenario around shift work, CD and internal cancers provides a unique case for "white-box" epidemiology: Research at many levels - from sub-cellular biochemistry, to whole cells, to organs, to organisms, including animals and humans - has suggested a series of quite precise and partly related causal mechanisms. This is in stark contrast to instances of "black box" or "stabs in the dark" epidemiology where causal mechanisms are neither known nor hypothesized or only poorly defined. The overriding theme that an adequate chronobiological organization of physiology can be critical for the protection against cancer builds the cornerstone of biological plausibility in this case.We can now benefit from biological plausibility in two ways: First, epidemiology should use biologically plausible insights into putative chains of causation between shift work and cancer to design future investigations. Second, when significant new data were to become available in coming years, IARC will re-evaluate cancer hazards associated with shift work. Biological plausibility may then be a key viewpoint to consider and, ultimately, to decide whether (or not) to pass

    The human Ureaplasma species are the most frequently isolated microorganisms from the amniotic fluid and placentae of women who deliver preterm and are also associated with spontaneous abortions or miscarriages, neonatal respiratory diseases, and chorioamnionitis. Despite the fact that these microorganisms have been habitually found within placentae of pregnancies with chorioamnionitis, the role of Ureaplasma species as a causative agent has not been satisfactorily explained. There is also controversy surrounding their role in disease, particularly as not all women infected with Ureaplasma spp. develop chorioamnionitis. In this review, we provide evidence that Ureaplasma spp. are associated with diseases of pregnancy and discuss recent findings which demonstrate that Ureaplasma spp. are associated with chorioamnionitis, regardless of gestational age at the time of delivery. Here, we also discuss the proposed major virulence factors of Ureaplasma spp., with a focus on the multiple-banded antigen (MBA), which may facilitate modulation/alteration of the host immune response and potentially explain why only subpopulations of infected women experience adverse pregnancy outcomes. The information presented within this review confirms that Ureaplasma spp. are not simply "innocent bystanders" in disease and highlights that these microorganisms are an often underestimated pathogen of pregnancy.

  20. Statistical Mechanics of Labor Markets

    NASA Astrophysics Data System (ADS)

    Chen, He; Inoue, Jun-ichi

    We introduce a probabilistic model of labor markets for university graduates, in particular, in Japan. To make a model of the market efficiently, we take into account several hypotheses. Namely, each company fixes the (business year independent) number of opening positions for newcomers. The ability of gathering newcomers depends on the result of job matching process in past business years. This fact means that the ability of the company is weaken if the company did not make their quota or the company gathered applicants too much over the quota. All university graduates who are looking for their jobs can access the public information about the ranking of companies. Assuming the above essential key points, we construct the local energy function of each company and describe the probability that an arbitrary company gets students at each business year by a Boltzmann-Gibbs distribution. We evaluate the relevant physical quantities such as the employment rate. We find that the system undergoes a sort of `phase transition' from the `good employment phase' to `poor employment phase' when one controls the degree of importance for the ranking.

    The Pacific broad tapeworm Adenocephalus pacificus (syn. Diphyllobothrium pacificum) is the causative agent of the third most common fish-borne cestodosis among humans. Although most of the nearly 1,000 cases among humans have been reported in South America (Peru, Chile, and Ecuador), cases recently imported to Europe demonstrate the potential for spread of this tapeworm throughout the world as a result of global trade of fresh or chilled marine fish and travel or migration of humans. We provide a comprehensive survey of human cases of infection with this zoonotic parasite, summarize the history of this re-emerging disease, and identify marine fish species that may serve as a source of human infection when eaten raw or undercooked.

  2. Editorial Commentary: Evaluating the Epidemiology of Shoulder Stabilization Surgery: An Opinion on Causation.

    PubMed

    Nelson, Bradley

    2018-03-01

    Epidemiology originates from the Greek words "epi" meaning upon and "demos" meaning people. Hence, epidemiology is the study of what is "upon the people" or the analysis of the patterns of disease in a defined population. Epidemiological studies are important in defining "at-risk" patient populations so research can be directed toward these groups. It is important to understand that epidemiology does not determine causation. However, it is reasonable for clinicians (me) to opine on the reasons for these epidemiological trends. I believe that the major factors responsible for the changing incidence in shoulder stabilization are the use of the arthroscope and the surgical management of the first time dislocator.

    Human sparganosis is one of the neglected diseases but important food-borne parasitic zoonoses. The disease is caused by larvae (spargana) of diphyllobothriidean tapeworm. Here, we describe nine cases of human sparganosis, caused by Spirometra erinaceieuropaei in a hospital in Thailand during 2001–2012. Clinical characteristics, treatment, and outcome of cases were revealed. Diagnosis and identification of causative parasite species was made by histopathological investigations followed by a polymerase chain reaction-based molecular method using formalin-fixed paraffin embedded tissues. The DNA samples were extracted from tissues and a partial fragment of cytochrome c oxidase subunit 1 (cox1) gene was amplified for the detection of parasitic DNA. Infection could be prevented by increasing activities on health communication by responsible public health agencies. PMID:24842879

  4. Non-Reflective Thinkers Are Predisposed to Attribute Supernatural Causation to Uncanny Experiences.

    2015-07-01

    For unknown reasons, individuals who are confident in their intuitions are more likely to hold supernatural beliefs. How does an intuitive cognitive style lead one to believe in faith healing, astrology, or extrasensory perception (ESP)? We hypothesize that cognitive style is critically important after one experiences an uncanny event that seems to invite a supernatural explanation. In three studies, we show that irrespective of their prior beliefs in the supernatural, non-reflective thinkers are more likely than reflective thinkers to accept supernatural causation after an uncanny encounter with astrology and ESP. This is the first time that controlled experiments demonstrate the negative dynamics of reflection and supernatural causality attribution. We consider the possible generalization of our findings to religious beliefs and their implications for the social vulnerability of non-reflective individuals. © 2015 by the Society for Personality and Social Psychology, Inc.

  9. Network marketing on a small-world network

    2006-02-01

    We investigate a dynamic model of network marketing in a small-world network structure artificially constructed similarly to the Watts-Strogatz network model. Different from the traditional marketing, consumers can also play the role of the manufacturer's selling agents in network marketing, which is stimulated by the referral fee the manufacturer offers. As the wiring probability α is increased from zero to unity, the network changes from the one-dimensional regular directed network to the star network where all but one player are connected to one consumer. The price p of the product and the referral fee r are used as free parameters to maximize the profit of the manufacturer. It is observed that at α=0 the maximized profit is constant independent of the network size N while at α≠0, it increases linearly with N. This is in parallel to the small-world transition. It is also revealed that while the optimal value of p stays at an almost constant level in a broad range of α, that of r is sensitive to a change in the network structure. The consumer surplus is also studied and discussed.

  10. Picking the right transition strategy.

    PubMed

    Watkins, Michael D

    2009-01-01

    Leaders in transition reflexively rely on the skills and strategies that worked for them in the past. That's a mistake, says Watkins, whose research shows that executives moving into new roles must gain a deep understanding of the situation at hand and adapt to it. To help them accurately assess their organizations and tailor their strategies and styles accordingly, he developed the STARS framework. "STARS" is an acronym for the five common situations leaders move into: start-up, turnaround, accelerated growth, realignment, and sustaining success. Thus, the model outlines the challenges of launching a venture or project; saving a business or initiative that's in serious trouble; dealing with rapid expansion; reenergizing a once-leading company that's now facing problems; and following in the footsteps of a highly regarded leader with a strong legacy of success. Executives can accelerate their immersion in new roles by following certain fundamental principles: Organize to learn about the business, establish A-item priorities, define strategic intent, quickly build the leadership team, secure early wins, and create supportive alliances across the company. But the way those principles should be applied depends very much on the business situation, which the STARS framework can help leaders analyze. Turnarounds and realignments present especially distinct leadership challenges that call for particular transition strategies. Regardless of the business situation, leaders must figure out which things need to happen--perhaps a jump in market share or an expansion into different markets--for their business to achieve its goals. And they must determine which leadership style best fits the new culture they're joining. Armed with such clarity, executives can design effective plans to manage their organizations and themselves.

    2010-01-01

    We use generating functional analysis to study minority-game-type market models with generalized strategy valuation updates that control the psychology of agents' actions. The agents' choice between trend-following and contrarian trading, and their vigor in each, depends on the overall state of the market. Even in 'fake history' models, the theory now involves an effective overall bid process (coupled to the effective agent process) which can exhibit profound remanence effects and new phase transitions. For some models the bid process can be solved directly, others require Maxwell-construction-type approximations.

    Motor vehicle crash (MVC)-related spinal injuries result in significant morbidity and mortality in children. The objective was to identify MVC-related injury causation scenarios for spinal injuries in restrained children. This was a case series of occupants in MVCs from the Crash Injury Research and Engineering Network (CIREN) data set. Occupants aged 0-17 years old with at least one Abbreviated Injury Scale (AIS) 2+ severity spinal injury in vehicles model year 1990+ that did not experience a rollover were included. Unrestrained occupants, those not using the shoulder portion of the belt restraint, and those with child restraint gross misuse were excluded. Occupants with preexisting comorbidities contributing to spinal injury and occupants with limited injury information were also excluded. A multidisciplinary team retrospectively reviewed each case to determine injury causation scenarios (ICSs). Crash conditions, occupant and restraint characteristics, and injuries were qualitatively summarized. Fifty-nine cases met the study inclusion criteria and 17 were excluded. The 42 occupants included sustained 97 distinct AIS 2+ spinal injuries (27 cervical, 22 thoracic, and 48 lumbar; 80 AIS-2, 15 AIS-3, 1 AIS-5, and 1 AIS-6), with fracture as the most common injury type (80%). Spinal-injured occupants were most frequently in passenger cars (64%), and crash direction was most often frontal (62%). Mean delta-V was 51.3 km/h±19.4 km/h. The average occupant age was 12.4±5.3 years old, and 48% were 16- to 17-year-olds. Thirty-six percent were right front passengers and 26% were drivers. Most occupants were lap and shoulder belt restrained (88%). Non-spinal AIS 2+ injuries included those of the lower extremity and pelvis (n=56), head (n=43), abdomen (n=39), and thorax (n=36). Spinal injury causation was typically due to flexion or lateral bending over the lap and or shoulder belt or child restraint harness, compression by occupant's own seat back, or axial loading through

  16. Morbid obesity and the transition from welfare to work.

    PubMed

    Cawley, John; Danziger, Sheldon

    2005-01-01

    This paper utilizes a rich longitudinal data set--the Women's Employment Study (WES)--to investigate whether obesity, which is common among women of low socioeconomic status, is a barrier to employment and earnings for current and former welfare recipients. We find that former welfare recipients who are both White and morbidly obese have been less successful in transitioning from welfare to work. These women are less likely to work at any survey wave, spend a greater percentage of months between waves receiving cash welfare, and have lower monthly earnings at each wave. The magnitude of the difference in labor market outcomes between the morbidly obese and those who are less heavy is in some cases similar in magnitude to the differences in these labor market outcomes between high school dropouts and graduates. In contrast, we find no such labor market differences associated with morbid obesity for African-American respondents. This paper documents the relationship between weight and labor market outcomes for the first time among the welfare population. In addition, it investigates whether the correlation for White females is due to unobserved heterogeneity. We find that after controlling for individual fixed effects, the point estimate of the correlation of morbid obesity and each of the labor market outcomes falls considerably and is no longer statistically significant. These results are consistent with unobserved heterogeneity causing the correlation between morbid obesity and labor market outcomes. Findings are similar after controlling for the respondent's mental and physical health.

    Cyst infection is a frequent and serious complication of autosomal dominant polycystic kidney disease (ADPKD). Lipid-soluble antibiotics like fluoroquinolones show good penetration into cysts and are recommended for cyst infection, but causative microorganisms are often resistant to these agents. This study investigated the profile of the microorganisms causing cyst infection in ADPKD, their susceptibility to lipid-soluble antibiotics, and clinical outcomes. This retrospective study reviewed all ADPKD patients admitted to Toranomon Hospital with a diagnosis of cyst infection from January 2004 to March 2014. All patients who underwent cyst drainage and had positive cyst fluid cultures were enrolled. Patients with positive blood cultures who satisfied our criteria for cyst infection or probable infection were also enrolled. There were 99 episodes with positive cyst fluid cultures and 93 episodes with positive blood cultures. The majority of patients were on dialysis. The death rate was high when infection was caused by multiple microorganisms or when there were multiple infected cysts. Gram-negative bacteria accounted for 74-79 % of the isolates in all groups, except for patients with positive hepatic cyst fluid cultures. The susceptibility of Escherichia coli to fluoroquinolones was very low in patients with hepatic cyst infection, especially those with frequent episodes and those with hepatomegaly. Fungi were detected in two episodes. Fluoroquinolone-resistant microorganisms showed a high prevalence in cyst infection. It is important to identify causative microorganisms to avoid the overuse of fluoroquinolones and to improve the outcome of cyst infection in ADPKD.

  19. Does the market maker stabilize the market?

    NASA Astrophysics Data System (ADS)

    Zhu, Mei; Chiarella, Carl; He, Xue-Zhong; Wang, Duo

    2009-08-01

    The market maker plays an important role in price formation, but his/her behavior and stabilizing impact on the market are relatively unclear, in particular in speculative markets. This paper develops a financial market model that examines the impact on market stability of the market maker, who acts as both a liquidity provider and an active investor in a market consisting of two types of boundedly rational speculative investors-the fundamentalists and trend followers. We show that the market maker does not necessarily stabilize the market when he/she actively manages the inventory to maximize profits, and that rather the market maker’s impact depends on the behavior of the speculators. Numerical simulations show that the model is able to generate outcomes for asset returns and market inventories that are consistent with empirical findings.

    2008-02-01

    This article reviews critical linkages between land-use transition and human health in the Himalayan region by applying ecosystem approaches to human health (or EcoHealth). Land-use transition in the Himalayan and similar regions includes sedentarization, agricultural intensification, habitat modification, migration, change of livelihoods and lifestyles, biodiversity loss, and increasing flash floods. These transitions, which can have impacts on human health, are driven by state policies, a market economy, and climate change. Human health is dependent on access to ecosystem services for food, nutrition, medicine, fiber and shelter, fresh water, and clear air. Ecosystem management has been a key means of controlling disease vectors and creating suitable habitats for human well-being. The paper identifies the web of environmental factors that influence human health. Institutional and policy issues for land-use and health transitions are also discussed.

  8. Clinical outcomes with daptomycin: a post-marketing, real-world evaluation.

    PubMed

    Sakoulas, G

    2009-12-01

    The Cubicin Outcomes Registry and Experience (CORE) is an ongoing, retrospective, post-marketing database of daptomycin use in the USA. Although non-comparative, CORE offers insight into real-life clinical experience with daptomycin in various Gram-positive infections and specific patient types. Analyses of daptomycin treatment outcomes using the CORE database revealed that treatment with daptomycin has resulted in high rates of clinical success for a variety of Gram-positive infections, including indicated infections such as complicated skin and soft tissue infections, Staphylococcus aureus bacteraemia and right-sided infective endocarditis, and non-indicated infections such as osteomyelitis. Treatment outcomes did not differ significantly according to the causative pathogen for any of the analyses performed and were not influenced by the vancomycin MIC. Patients frequently received therapy with alternative antibiotics prior to treatment with daptomycin, particularly those patients with more serious infections. However, similar treatment outcomes were observed when daptomycin was used as first-line therapy or as salvage therapy, demonstrating the effectiveness of daptomycin in the treatment of these patients.

    2017-08-01

    This paper approaches the question of space dimensionality by discussing a neglected argument proposed by Hermann Weyl in 1955. In Why is the World Four-Dimensional? (1955), Weyl offered a different argument from the one generally attributed to him and presented in Raum-Zeit-Materie. In the first sections of the paper, this new argument and its features are spelled-out, and in the last section, I shall develop some useful remarks on the concept of topology of causation that can still inform our reflection on the dimensionality of the world.

    Tracking and trending rates of injuries and illnesses classified as musculoskeletal disorders caused by ergonomic risk factors such as overexertion and repetitive motion (MSDs) and slips, trips, or falls (STFs) in different industry sectors is of high interest to many researchers. Unfortunately, identifying the cause of injuries and illnesses in large datasets such as workers' compensation systems often requires reading and coding the free form accident text narrative for potentially millions of records. To alleviate the need for manual coding, this paper describes and evaluates a computer auto-coding algorithm that demonstrated the ability to code millions of claims quickly and accurately by learning from a set of previously manually coded claims. The auto-coding program was able to code claims as a musculoskeletal disorders, STF or other with approximately 90% accuracy. The program developed and discussed in this paper provides an accurate and efficient method for identifying the causation of workers' compensation claims as a STF or MSD in a large database based on the unstructured text narrative and resulting injury diagnoses. The program coded thousands of claims in minutes. The method described in this paper can be used by researchers and practitioners to relieve the manual burden of reading and identifying the causation of claims as a STF or MSD. Furthermore, the method can be easily generalized to code/classify other unstructured text narratives. Published by Elsevier Ltd.

    1976-10-01

    Colonic cancer is rare in primitive populations. In western populations it was uncommon in the past, but now accounts for about 3% of all deaths. The cause almost certainly lies with dietary changes. Probably, alterations in bowel milieu interieur, from interaction between metabolites and microbacteria, promote carcinogenesis. Changes in intakes of protein, fat, sugar, refined cereal products, and crude fiber have been advanced as predisposing or causative factors. Evidence suggests that (i) fall in fiber intake, but (ii) rise in fat intake, in their ability to increase fecal concentrations of bile acids and sterols (possible precursors of carcinogens) are most likely to be culpable. As preventive measures, a significant rise in fiber intake is practicable only from regular bran ingestion. A major reduction in fat intake is grossly unlikely. Even were rigorous dietary changes implemented, an early fall in colonic cancer incidence is highly improbable due to the long-term character of the disease. Future research must include characterization of the diet, metabolism, and disease pattern of segments of western populations who have low colonic cancer mortality rates; also, elucidation of the bearing of various intakes of different food components on the biochemistry and microbiology of the feces.

    Forward genetics screens with N-ethyl-N-nitrosourea (ENU) provide a powerful way to illuminate gene function and generate mouse models of human disease; however, the identification of causative mutations remains a limiting step. Current strategies depend on conventional mapping, so the propagation of affected mice requires non-lethal screens; accurate tracking of phenotypes through pedigrees is complex and uncertain; out-crossing can introduce unexpected modifiers; and Sanger sequencing of candidate genes is inefficient. Here we show how these problems can be efficiently overcome using whole-genome sequencing (WGS) to detect the ENU mutations and then identify regions that are identical by descent (IBD) in multiple affected mice. In this strategy, we use a modification of the Lander-Green algorithm to isolate causative recessive and dominant mutations, even at low coverage, on a pure strain background. Analysis of the IBD regions also allows us to calculate the ENU mutation rate (1.54 mutations per Mb) and to model future strategies for genetic screens in mice. The introduction of this approach will accelerate the discovery of causal variants, permit broader and more informative lethal screens to be used, reduce animal costs, and herald a new era for ENU mutagenesis.

  15. Evolution of sexual dimorphism in bill size and shape of hermit hummingbirds (Phaethornithinae): a role for ecological causation

    PubMed Central

    Temeles, Ethan J.; Miller, Jill S.; Rifkin, Joanna L.

    2010-01-01

    Unambiguous examples of ecological causation of sexual dimorphism are rare, and the best evidence involves sexual differences in trophic morphology. We show that moderate female-biased sexual dimorphism in bill curvature is the ancestral condition in hermit hummingbirds (Phaethornithinae), and that it is greatly amplified in species such as Glaucis hirsutus and Phaethornis guy, where bills of females are 60 per cent more curved than bills of males. In contrast, bill curvature dimorphism is lost or reduced in a lineage of short-billed hermit species and in specialist Eutoxeres sicklebill hermits. In the hermits, males tend to be larger than females in the majority of species, although size dimorphism is typically small. Consistent with earlier studies of hummingbird feeding performance, both raw regressions of traits and phylogenetic independent contrasts supported the prediction that dimorphism in bill curvature of hermits is associated with longer bills. Some evidence indicates that differences between sexes of hermit hummingbirds are associated with differences in the use of food plants. We suggest that some hermit hummingbirds provide model organisms for studies of ecological causation of sexual dimorphism because their sexual dimorphism in bill curvature provides a diagnostic clue for the food plants that need to be monitored for studies of sexual differences in resource use.

    2015-12-01

    According to the Russo-Williamson Thesis, causal claims in the health sciences need to be supported by both difference-making and mechanistic evidence. In this article, we attempt to determine whether Evidence-based Medicine (EBM) can be improved through the consideration of mechanistic evidence. We discuss the practical composition and function of each RWT evidence type and propose that exposure-outcome evidence (previously known as difference-making evidence) provides associations that can be explained through a hypothesis of causation, while mechanistic evidence provides finer-grained associations and knowledge of entities that ultimately explains a causal hypothesis. We suggest that mechanistic evidence holds untapped potential to add value to the assessment of evidence quality in EBM and propose initial recommendations for the integration of mechanistic and exposure-outcome evidence to improve EBM by robustly leveraging available evidence in support of good medical decisions.

    Field of study may influence the timing of transitions to the labor market, marriage, and parenthood among college graduates. Research to date has yet to study how field of study is associated with the interweaving of these transitions in the USA. The current study examines gendered influences of college field of study on transitions to a series of adult roles, including full-time work, marriage, and parenthood. We use Cox proportional hazards models and multinomial logistic regression to examine gendered associations between field of study and the three transitions among college graduates of the NLSY97 (National Longitudinal Survey of Youth) cohort. Men majoring in STEM achieve early transitions to full-time work, marriage, and parenthood; women majoring in STEM show no significant advantage in finding full-time work and delayed marriage and childbearing; women in business have earlier transitions to full-time work and marriage than women in other fields, demonstrating an advantage similar to that of men in STEM. The contrast between men and women in STEM shows that transition to adulthood remains gendered; the contrast between women in STEM and women in business illustrates that a prestigious career may not necessarily delay family formation.

  19. Religion, Marriage Markets, and Assortative Mating in the United States

    2016-01-01

    As interfaith marriage has become more common, religion is thought to be less important for sorting partners. However, prior studies on religious assortative mating use samples of prevailing marriages, which miss how local marriage markets shape both partner selection and marriage timing. Drawing on search theory and data from 8,699 young adults (ages 18–31) in the National Longitudinal Study of Youth 1997, the author examined the association between the concentration of co-religionists in local marriage markets and marriage timing and partner selection using event history methods. Religious concentration is associated with higher odds of transitioning to marriage and religious homogamy (conditional on marriage) for women and men at older ages (24–31) but not at younger ages (18–23). The association was also stronger for non-Hispanic Whites compared to other race-ethnic groups. The findings indicate that religion remains relevant in sorting partners for many young adults in today’s marriage market. PMID:27818530

    To investigate evolving food retail systems in Thailand. Rapid assessment procedures based on qualitative research methods including interviews, focus groups discussions and site visits. Seven fresh markets located in the four main regions of Thailand. Managers, food specialists, vendors and shoppers from seven fresh markets who participated in interviews and focus group discussions. Fresh markets are under economic pressure and are declining in number. They are attempting to resist the competition from supermarkets by improving convenience, food diversity, quality and safety. Obesity has increased in Thailand at the same time as rapid growth of modern food retail formats has occurred. As fresh markets are overtaken by supermarkets there is a likely loss of fresh, healthy, affordable food for poorer Thais, and a diminution of regional culinary culture, women's jobs and social capital, with implications for the health and nutrition transition in Thailand.

    2016-01-01

    Occupational tasks of linemen are highly associated with the development of work related musculoskeletal disorders (WRMDs). Although linemen are prone to develop WRMDs, there is paucity of information on the prevalence of WRMDs and related occupational causative factors. Therefore, the present review was conducted to report on the prevalence of WRMDs and to outline causative risk factors within occupational tasks in the lineman profession. Literature search was conducted in various databases such as Scopus, PubMed and ScienceDirect for articles published between 1996-2013. The articles were analyzed, selected and retrieved based on predetermined objectives, inclusion criteria and Medical Subject Headings (MeSH). In the review process only articles published in English were considered. The review identified moderate to high prevalence of WRMDs among the linemen population. Back and shoulder regions were highly affected compared to the other body regions. The review also reported occupational tasks such as bar installation, insulator fixation and manual handling of tools as high risk tasks that lead to the development of WRMDs. In addition, occupational tools such as ladders, manual cutters and manual presses were also identified as a potential ergonomic hazard. In conclusion, the current review identified that WRMDs are common in the back and shoulder regions among linemen. Also, a number of occupational risk factors were identified to be associated with WRMDs among the linemen. Hence, future research on prevention and intervention studies concerning lineman profession population in order to develop a good job practice are recommended.

    2010-01-01

    This article investigates the effect of family life course transitions on labor allocation strategies in rural Chinese households. We highlight three types of economic activity that involve reallocation of household labor oriented toward a more diversified, nonfarm rural economy: involvement in wage employment, household entrepreneurship, and/or multiple activities that span economic sectors. With the use of data from the China Health and Nutrition Survey (CHNS 1997, 2000, and 2004), our longitudinal analyses of rural household economic activity point to the significance of household demography, life course transitions, and local economic structures as factors facilitating household labor reallocation. First, as expected, a relatively youthful household structure is conducive to innovative economic behavior. Second, household entrances and exits are significant, but their impacts are not equal. Life events such as births, deaths, marriage, or leaving home for school or employment affect household economy in distinctive ways. Finally, the reallocations of household labor undertaken by households are shaped by local economic structures: in particular, the extent of village-level entrepreneurial activity, off-farm employment, and out-migration.

    2015-12-01

    We introduced Evidence-based Toxicology (EBT) in 2005 to address the disparities that exist between the various Weight-of-Evidence (WOE) methods typically applied in the regulatory hazard decision-making arena and urged toxicologists to adopt the evidence-based guidelines long-utilized in medicine (i.e., Evidence-Based Medicine or EBM). This review of the activities leading to the adoption of evidence-based methods and EBT during the last decade demonstrates how fundamental concepts that form EBT, such as the use of systematic reviews to capture and consider all available information, are improving toxicological evaluations performed by various groups and agencies. We reiterate how the EBT framework, a process that provides a method for performing human chemical causation analyses in an objective, transparent and reproducible manner, differs significantly from past and current regulatory WOE approaches. We also discuss why the uncertainties associated with regulatory WOE schemes lead to a definition of the term "risk" that contains unquantifiable uncertainties not present in this term as it is used in epidemiology and medicine. We believe this distinctly different meaning of "risk" should be clearly conveyed to those not familiar with this difference (e.g., the lay public), when theoretical/nomologic risks associated with chemical-induced toxicities are presented outside of regulatory and related scientific parlance. © The Author(s) 2015.

  4. Gout and arrhythmias: In search for causation beyond association.

    PubMed

    2018-06-13

    Gout is a systemic disease, characterized by the formation and deposition of crystals in tissues (mainly in and around the joints) of individuals with elevated serum uric acid levels. Lately, a considerable number of reports relating elevated uric acid and/or gout with rhythm disorders, such as atrial fibrillation, have been published. This review summarizes evidence linking common arrhythmias and hyperuricemia/gout and discusses questions or controversies that surround it. Overall, existing evidence may not be overwhelming, but strongly suggests a positive correlation between uric acid levels and common rhythm disorders. Needless to say that such a link - as a univariate association between the two - is to be expected, given the extensive overlap of risk factors and comorbidities of hyperuricemia/gout and arrhythmias. However, the observed associations seem to persist - in most studies - after extensive adjustment for potential confounders. Still, multivariable analyses of epidemiologically collected data cannot substitute for proof coming from basic and clinical studies. There is obviously a need for further basic research to establish a causal relationship between uric acid effects and arrhythmias, as well as translational studies and clinical trials to investigate the therapeutic implications of such a relationship. Simply put, we are fairly certain that there is association, but proof of causation is what we are still in want of. Copyright © 2018. Published by Elsevier Inc.

    Mikrocytos mackini, causative agent of Denman Island disease in Pacific oysters Crassostrea gigas and other oyster species, was found in 2011 in a previously unreported host, the Kumamoto oyster C. sikamea, in Humboldt Bay, California, USA. The detection was also the first reported finding of M. mackini in California. Prevalence was estimated as high as approximately 27% from pooled samples analyzed by PCR. Higher prevalence appeared related to longer residence time in the bay and somewhat colder than typical winter seawater temperatures. No M. mackini was detected in Humboldt Bay juvenile Kumamoto oysters or Pacific oyster brood or seed stock in 2011 or 2012.

  7. Cholesterol as a Causative Factor in Alzheimer Disease: A Debatable Hypothesis

    PubMed Central

    Wood, W. Gibson; Li, Ling; Müller, Walter E.; Eckert, Gunter P.

    2014-01-01

    High serum/plasma cholesterol levels have been suggested as a risk factor for Alzheimer disease (AD). Some reports, mostly retrospective epidemiological studies, have observed a decreased prevalence of AD in patients taking the cholesterol lowering drugs, statins. The strongest evidence causally linking cholesterol to AD is provided by experimental studies showing that adding/reducing cholesterol alters amyloid precursor protein (APP) and amyloid beta-protein (Aβ) levels. However, there are problems with the cholesterol-AD hypothesis. Cholesterol levels in serum/plasma and brain of AD patients do not support cholesterol as a causative factor in AD. Prospective studies on statins and AD have largely failed to show efficacy. Even the experimental data are open to interpretation given that it is well-established that modification of cholesterol levels has effects on multiple proteins, not only APP and Aβ. The purpose of this review, therefore, is to examine the above-mentioned issues and discuss the pros and cons of the cholesterol-AD hypothesis, and the involvement of other lipids in the mevalonate pathway, such as isoprenoids and oxysterols, in AD.

    2017-08-01

    Tinea capitis is a dermatophyte infection common among prepubertal children in sub-Saharan Africa and mainly caused by Trichophyton and Microsporum species. Accurate identification is challenging as conventional methods like culture and microscopy are slow and mostly based on morphological characteristics, which make them less sensitive and specific. Modern molecular methods, like polymerase chain reaction (PCR) assays, are gaining acceptance and are quick as well as accurate. The aim of this study was to investigate the clinical patterns of tinea capitis and to accurately identify the most common causative dermatophytes affecting the scalps of children aged 1 to 16 years attending the Skin Clinic at Mbarara University of Science and Technology (MUST), Mbarara, Uganda, East Africa, using both conventional mycological methods and PCR-ELISA for detection of dermatophyte DNA. One hundred fifteen clinical samples from children from Western Uganda attending the MUST Skin Clinic with a clinical diagnosis of tinea capitis were analyzed. T. violaceum was identified as the most common causative agent, followed by M. audouinii, T. soudanense, and T. rubrum. The early identification of the causative agent of tinea capitis is a prerequisite for the effective management of the disease, the identification of probable source and the prevention of spreading. Children with tinea capitis in Western Uganda should be treated by systemic therapy rather than topical preparations to ensure high cure rates as the most common causative dermatophytes T. violaceum exhibits an endothrix rather than ectothrix invasion of the hair follicle. © The Author 2016.

    2016-01-01

    We describe herein two tumor-induced osteomalacia (TIO) cases for whom the causative lesions, located in their popliteal fossa, that were not identified in the standard field of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT), which usually images only the head, trunk, and proximal parts of the extremities. A 47 years old Japanese man with multiple pathological fractures due to osteomalacia, accompanied by muscle weakness, hypophosphatemia, and an elevation of alkaline phosphatase (ALP) was referred to our hospital. A (18)F-FDG PET/CT scan was performed, but no (18)F-FDG uptake was detected in the standard field of imaging. Magnetic resonance imaging revealed a small subcutaneous tumor (1.9×1.2×0.6cm) of the left posteriomedial knee, displaying uniform enhancement on gadolinium-enhanced T1-weighted fat-suppression imaging. The tumor was resected widely and diagnosed as phosphaturic mesenchymal tumor, mixed connective tissue variant (PMTMCT). The other patient was a 31 years old Japanese woman with multiple pathological fractures, hypophosphatemia and elevated of ALP and was referred to our hospital on suspicion of TIO. Although the causative lesion was not identified in the standard field of (18)F-FDG PET/CT, (18)F-FDG uptake (SUVmax 2.9) was detected on the right knee in the additional whole-body (18)F-FDG PET/CT. Magnetic resonance imaging revealed a soft-tissue tumor (6.4×4.1×2.9cm) in the right posterior knee. Following biopsy, the tumor was marginally resected, and was pathologically diagnosed as PMTMCT. Once patients are suspected to have TIO, a whole-body nuclear imaging study such as (18)F-FDG PET/CT should be performed, in order not to miss the hidden causative tumor, especially occurring in the distal extremities.

    Objective Motor vehicle crash (MVC)-related spinal injuries result in significant morbidity and mortality in children. The objective was to identify MVC-related injury causation scenarios for spinal injuries in restrained children. Methods This was a case series of occupants in MVCs from the Crash Injury Research and Engineering Network (CIREN) data set. Occupants aged 0–17 years old with at least one Abbreviated Injury Scale (AIS) 2+ severity spinal injury in vehicles model year 1990+ that did not experience a rollover were included. Unrestrained occupants, those not using the shoulder portion of the belt restraint, and those with child restraint gross misuse were excluded. Occupants with preexisting comorbidities contributing to spinal injury and occupants with limited injury information were also excluded. A multidisciplinary team retrospectively reviewed each case to determine injury causation scenarios (ICSs). Crash conditions, occupant and restraint characteristics, and injuries were qualitatively summarized. Results Fifty-nine cases met the study inclusion criteria and 17 were excluded. The 42 occupants included sustained 97 distinct AIS 2+ spinal injuries (27 cervical, 22 thoracic, and 48 lumbar; 80 AIS-2, 15 AIS-3, 1 AIS-5, and 1 AIS-6), with fracture as the most common injury type (80%). Spinal-injured occupants were most frequently in passenger cars (64%), and crash direction was most often frontal (62%). Mean delta-V was 51.3 km/h ± 19.4 km/h. The average occupant age was 12.4 ± 5.3 years old, and 48% were 16- to 17-year-olds. Thirty-six percent were right front passengers and 26% were drivers. Most occupants were lap and shoulder belt restrained (88%). Non-spinal AIS 2+ injuries included those of the lower extremity and pelvis (n = 56), head (n = 43), abdomen (n = 39), and thorax (n = 36). Spinal injury causation was typically due to flexion or lateral bending over the lap and or shoulder belt or child restraint harness, compression by occupant

    Non-centralized recommendation-based decision making is a central feature of several social and technological processes, such as market dynamics, peer-to-peer file-sharing and the web of trust of digital certification. We investigate the properties of trust propagation on networks, based on a simple metric of trust transitivity. We investigate analytically the percolation properties of trust transitivity in random networks with arbitrary in/out-degree distributions, and compare with numerical realizations. We find that the existence of a non-zero fraction of absolute trust (i.e. entirely confident trust) is a requirement for the viability of global trust propagation in large systems: The average pair-wise trust is marked by a discontinuous transition at a specific fraction of absolute trust, below which it vanishes. Furthermore, we perform an extensive analysis of the Pretty Good Privacy (PGP) web of trust, in view of the concepts introduced. We compare different scenarios of trust distribution: community- and authority-centered. We find that these scenarios lead to sharply different patterns of trust propagation, due to the segregation of authority hubs and densely-connected communities. While the authority-centered scenario is more efficient, and leads to higher average trust values, it favours weakly-connected "fringe" nodes, which are directly trusted by authorities. The community-centered scheme, on the other hand, favours nodes with intermediate in/out-degrees, in detriment of the authorities and its "fringe" peers.

    In the second half of the twentieth century, epidemiology came to shape public health discourses and practices to an unprecedented extent. The chapter explores the transformation of the discipline after World War Two and analyses the crucial debate on the notion of "causation" that sprung from the growing interest in non-transmissible, chronic diseases. A landmark in this history was the controversy over the interpretation of the statistical relationship between smoking and lung cancer prompted by American and British publications in 1950. This sometimes heated debate also provided Austin Bradford Hill with the opportunity to set out his "pragmatics" of risk factor epidemiology.

    Introduction Tracking and trending rates of injuries and illnesses classified as musculoskeletal disorders caused by ergonomic risk factors such as overexertion and repetitive motion (MSDs) and slips, trips, or falls (STFs) in different industry sectors is of high interest to many researchers. Unfortunately, identifying the cause of injuries and illnesses in large datasets such as workers’ compensation systems often requires reading and coding the free form accident text narrative for potentially millions of records. Method To alleviate the need for manual coding, this paper describes and evaluates a computer auto-coding algorithm that demonstrated the ability to code millions of claims quickly and accurately by learning from a set of previously manually coded claims. Conclusions The auto-coding program was able to code claims as a musculoskeletal disorders, STF or other with approximately 90% accuracy. Impact on industry The program developed and discussed in this paper provides an accurate and efficient method for identifying the causation of workers’ compensation claims as a STF or MSD in a large database based on the unstructured text narrative and resulting injury diagnoses. The program coded thousands of claims in minutes. The method described in this paper can be used by researchers and practitioners to relieve the manual burden of reading and identifying the causation of claims as a STF or MSD. Furthermore, the method can be easily generalized to code/classify other unstructured text narratives. PMID:23206504

    2011-12-15

    Transportation is vital to the U.S. economy and society. As such, U.S. Presidents have repeatedly stated that the nation needs to reduce dependence on petroleum, especially for the highway transportation sector. Throughout history, highway transportation fuel transitions have been completed successfully both in United States and abroad. Other attempts have failed, as described in Appendix A: Historical Highway Fuel Transitions. Planning for a transition is critical because the changes can affect our nation's ability to compete in the world market. A transition will take many years to complete. While it is tempting to make quick decisions about the new fuel(s)more » of choice, it is preferable and necessary to analyze all the pertinent criteria to ensure that correct decisions are made. Doing so will reduce the number of changes in highway fuel(s). Obviously, changes may become necessary because of occurrences such as significant technology breakthroughs or major world events. With any and all of the possible transitions to new fuel(s), the total replacement of gasoline and diesel fuels is not expected. These conventional fuels are envisioned to coexist with the new fuel(s) for decades, while the revised fuel and vehicle infrastructures are implemented. The transition process must analyze the needs of the primary 'players,' which consist of the customers, the government, the fuel industry, and the automotive industry. To maximize the probability of future successes, the prime considerations of these groups must be addressed. Section 2 presents a succinct outline of the Checklist. Section 3 provides a brief discussion about the groupings on the Checklist.« less

    Cleft lip with or without cleft palate (CL/P) is one of the most common birth defects worldwide and is characterized by abnormalities of the orofacial structure. Syndromic CL/P is mainly caused by Mendelian disorders such as Van der Woude Syndrome (VWS). However, >70% of CL/P cases are nonsyndromic, characterized by isolated orofacial cleft without any known syndrome. The etiology of nonsyndromic CL/P (NSCL/P) remains elusive, but it has been suggested that causative genes of syndromic CL/P might also contribute to NSCL/P. As such, the VWS causative gene IRF6 has been extensively studied in NSCL/P. Recently, GRHL3 was identified as another VWS causative gene. Thus, it may be a novel candidate gene for NSCL/P. In the present study, we genotyped 10 tag SNPs covering GRHL3 and performed association analysis with NSCL/P in 504 cases and 455 healthy controls. Our preliminary results identified rs10903078, rs4638975, and a haplotype rs10903078-rs6659209 of GRHL3 that exceeded the significance threshold (p<0.05), though none survived Bonferroni correction for multiple comparisons. As the first study between GRHL3 and NSCL/P, the contribution of this gene to NSCL/P etiology should be interpreted with caution based on existing evidence. Further, the robustness of association between GRHL3 and NSCL/P should be further validated in expanded cohorts. Copyright © 2016. Published by Elsevier B.V.

  2. Managing the transition to integrated health care organizations.

    PubMed

    Griffith, J R

    1996-01-01

    Today's successful community hospitals should and will evolve into integrated health care organizations (IHCOs) that will share several common characteristics. IHCOs will have a community--not a membership--orientation, and this will be a distinguishing characteristic and a source of market appeal. The transition to IHCO will be a slow one, and to prosper, the IHCO will have to accommodate both price-oriented markets and traditional ones. Successful IHCOs will expand technical skills and capabilities to control costs and quality. New strategic competencies will have to be developed, and to do this, emerging IHCOs will improve the ability of managers to support decisions and sell them both to the buyers and the public at large. Excellent patient care will rest upon better trained, advised, and informed management teams. Making the change to an IHCO will take time and money, but organizations that make steady progress are likely to succeed.

    This paper investigates the transition of dynamics observed in an actual real agricultural economic dataset. Lyapunov spectrum analysis is conducted on the data to distinguish deterministic chaos and the limit cycle. Chaotic and periodic oscillation were identified before and after the second oil crisis, respectively. The statitonarity of the time series is investigated using recurrence plots. This shows that government intervention might reduce market instability by removing a chaotic market's long-term unpredictability.

    BACKGROUND Field of study may influence the timing of transitions to the labor market, marriage, and parenthood among college graduates. Research to date has yet to study how field of study is associated with the interweaving of these transitions in the USA. OBJECTIVE The current study examines gendered influences of college field of study on transitions to a series of adult roles, including full-time work, marriage, and parenthood. METHODS We use Cox proportional hazards models and multinomial logistic regression to examine gendered associations between field of study and the three transitions among college graduates of the NLSY97 (National Longitudinal Survey of Youth) cohort. RESULTS Men majoring in STEM achieve early transitions to full-time work, marriage, and parenthood; women majoring in STEM show no significant advantage in finding full-time work and delayed marriage and childbearing; women in business have earlier transitions to full-time work and marriage than women in other fields, demonstrating an advantage similar to that of men in STEM. CONCLUSIONS The contrast between men and women in STEM shows that transition to adulthood remains gendered; the contrast between women in STEM and women in business illustrates that a prestigious career may not necessarily delay family formation.

  9. Hospital Value-Based Purchasing Performance: Do Organizational and Market Characteristics Matter?

    PubMed

    Spaulding, Aaron; Edwardson, Nick; Zhao, Mei

    The hospital value-based purchasing (HVBP) program of the Centers for Medicare & Medicaid Services challenges hospitals to deliver high-quality care or face a reduction in Medicare payments. How do different organizational structures and market characteristics enable or inhibit successful transition to this new model of value-based care? To address that question, this study employs an institutional theory lens to test whether certain organizational structures and market characteristics mediate hospitals' ability to perform across HVBP domains.Data from the 2014 American Hospital Association Annual Survey Database, Area Health Resource File, the Medicare Hospital Compare Database, and the association between external environment and hospital performance are assessed through multiple regression analysis. Results indicate that hospitals that belong to a system are more likely than independent hospitals to score highly on the domains associated with the HVBP incentive arrangement. However, varying and sometimes counterintuitive market influences bring different dimensions to the HVBP program. A hospital's ability to score well in this new value arrangement may be heavily based on the organization's ability to learn from others, implement change, and apply the appropriate amount of control in various markets.

    Lichen planus (LP) is a common skin disorder of unknown aetiology that affects the skin, mucous membranes and nails. Although metal allergies have been implicated in the development of oral LP (OLP), the contribution of these allergies to nail LP (NLP) has yet to be studied in detail. To elucidate the link between metal allergy and NLP. We retrospectively analysed 115 LP patients with respect to the contribution of metals to either NLP or OLP. We also attempted to detect the specific metals involved in these nail lesions. Of the 79 patients that received a metal patch test (PT), 24 (30%) were positive for at least one of the metal compounds tested. Notably, the prevalence of positive reactions to metals in the NLP patients was significantly higher as compared with the OLP patients (59% vs. 27%, P < 0.05). Among the 10 PT-positive patients with NLP, improvement of the skin lesions was seen in six of the patients after removal of dental materials containing causative metals or systemic disodium cromoglycate therapy. On the other hand, only 3 of 16 PT-positive patients with OLP exhibited improvement after the removal of dental materials. Causative metals in the dental fillings/braces were detected in the involved nail tissues. This study suggests that metal allergies are more closely associated with NLP vs. OLP, and that deposited metals in the nail apparatus contribute to the development of lichenoid tissue reactions in the nail bed and matrix. © 2012 The Authors.

    In this paper we have analyzed scaling properties and cyclical behavior of the three types of stock market indexes (SMI) time series: data belonging to stock markets of developed economies, emerging economies, and of the underdeveloped or transitional economies. We have used two techniques of data analysis to obtain and verify our findings: the wavelet transform (WT) spectral analysis to identify cycles in the SMI returns data, and the time-dependent detrended moving average (tdDMA) analysis to investigate local behavior around market cycles and trends. We found cyclical behavior in all SMI data sets that we have analyzed. Moreover, the positions and the boundaries of cyclical intervals that we found seam to be common for all markets in our dataset. We list and illustrate the presence of nine such periods in our SMI data. We report on the possibilities to differentiate between the level of growth of the analyzed markets by way of statistical analysis of the properties of wavelet spectra that characterize particular peak behaviors. Our results show that measures like the relative WT energy content and the relative WT amplitude of the peaks in the small scales region could be used to partially differentiate between market economies. Finally, we propose a way to quantify the level of development of a stock market based on estimation of local complexity of market's SMI series. From the local scaling exponents calculated for our nine peak regions we have defined what we named the Development Index, which proved, at least in the case of our dataset, to be suitable to rank the SMI series that we have analyzed in three distinct groups.

  13. Syphilis may be a confounding factor, not a causative agent, in syphilitic ALS.

    PubMed

    Tuk, Bert

    2016-01-01

    Based upon a review of published clinical observations regarding syphilitic amyotrophic lateral sclerosis (ALS), I hypothesize that syphilis is actually a confounding factor, not a causative factor, in syphilitic ALS. Moreover, I propose that the successful treatment of ALS symptoms in patients with syphilitic ALS using penicillin G and hydrocortisone is an indirect consequence of the treatment regimen and is not due to the treatment of syphilis. Specifically, I propose that the observed effect is due to the various pharmacological activities of penicillin G ( e.g ., a GABA receptor antagonist) and/or the multifaceted pharmacological activity of hydrocortisone. The notion that syphilis may be a confounding factor in syphilitic ALS is highly relevant, as it suggests that treating ALS patients with penicillin G and hydrocortisone-regardless of whether they present with syphilitic ALS or non-syphilitic ALS-may be effective at treating this rapidly progressive, highly devastating disease.

    As the healthcare marketplace, characterized by declining revenues and heavy price competition, continues to evolve toward managed care, teaching hospitals are being forced to act more like traditional industrial organizations. Profit-oriented behavior, including emphases on market strategies and competitive advantage, is now a necessity if these hospitals are going to survive the transition to managed care. To help teaching hospitals evaluate strategic options that maximize financial effectiveness, this study examined the financial and operating data for 100 major U.S. teaching hospitals to determine relationships among competitive strategy, market environment, and financial return on invested capital. Results should help major hospitals formulate more effective strategies to combat environmental turbulence.

    The purpose of this study was to present the impact of demography and market dynamics on the organizational and technological development of dental practices in Bulgaria during the period of socio-economic transition from 1990 to 2010. Relevant data were gathered from the official registers of the Bulgarian Dental Association, National Health Insurance Fund, National Health Information Institute and research studies, published during the period 1990-2010. They were analysed and are discussed in this paper. During the period there was a decrease in population of Bulgaria, from 8,149,468 in 2000 to 7,563,000 in 2010 and a movement from rural areas to cities. There was an aging population with an increase in oral health care needs at a time of decrease in the size of the national labour force and economic growth. Paradoxically, over the last 20 years, the number of dentists in Bulgaria increased by more than 50% from 1997 to 2008. The average age of dentists changed from 39.7 years in 1997 to 41.7 years in 2008. The number of group dental practices increased and the number of individual practices and group practices for specialized dental care and dental centres decreased. The utilization of dental services is currently "about half" that of the mean for all European Union Member States, which is over 80% per year. The growing number of elderly people who have retained their teeth suggests an increase in treatment needs. However, the decline in their purchasing power limits the demand for oral health care services. In order to meet this and other challenges Bulgarian dentists have started changing their traditional solo-practice to group-practice.

    2012-01-01

    This paper posits that rural migration feeds the high demand for cheap labor in peri-urbanization, which is driven by globalization, flows of foreign capital, and entrepreneurial local governments. While the gravity model and push/pull perspective ignore the dynamics of migratory course, we use the cumulative causation of migration theory to conceptualize social expectations for outmigration and social resources from migrant networks in destinations. Four major findings are drawn from this demographic analysis based on micro data from China's 2000 Census. First, the expectation of outmigration significantly increases outmigration, and this effect is independent of push factors. Second, foreign direct investment (FDI) contributes to attracting rural labor migrants from other provinces to peri-urban areas as it does to cities. Third, social resources from migrant networks play an important role in attracting rural labor migrants to both city and noncity destinations. Fourth, the importance of wage differentials declines in gravitating rural labor migrants to peri-urban areas. These findings provide tentative evidence that rural labor migration is indispensable during initial peri-urbanization. Infused with flows of FDI and entrepreneurial local governments, rural migration has created a favorable initial condition for peri-urbanization.

    Bartolozzi, M.; Thomas, A. W.

    2004-04-01

    In the present work we introduce a stochastic cellular automata model in order to simulate the dynamics of the stock market. A direct percolation method is used to create a hierarchy of clusters of active traders on a two-dimensional grid. Active traders are characterized by the decision to buy, σi (t)=+1 , or sell, σi (t)=-1 , a stock at a certain discrete time step. The remaining cells are inactive, σi (t)=0 . The trading dynamics is then determined by the stochastic interaction between traders belonging to the same cluster. Extreme, intermittent events, such as crashes or bubbles, are triggered by a phase transition in the state of the bigger clusters present on the grid, where almost all the active traders come to share the same spin orientation. Most of the stylized aspects of the financial market time series, including multifractal proprieties, are reproduced by the model. A direct comparison is made with the daily closures of the S&P500 index.

  1. Effective managed care marketing strategies for evolving markets.

    PubMed

    Conlon, M K

    1997-11-01

    In a world of increased competition and changing consumer expectations, one of the keys to a fiscally sound health plan is having a dynamic marketing strategy that takes into account the shifting attitudes of consumers as managed care markets mature. The primary goal of any health plan marketing strategy should be the acquisition and retention of members. Providing cost-efficient and convenient service for enrollees, offering low or no deductibles, having convenient office locations, and minimizing paper-work are important elements of such a marketing strategy. Factors such as brand awareness and the perceived image of a health plan also are important considerations in acquiring and retaining market share. The relative importance of these consumer satisfaction criteria change as a managed care market evolves and matures. Financial and marketing managers, thus, should ascertain their market's stage of development and respond with appropriate marketing strategies.

    Tinea capitis affects mainly children. The frequency and causative organism vary from region to region. To provide epidemiological and mycological data on tinea capitis collected in urban and rural areas of the Dominican Republic. Samples were obtained from 118 patients with tinea capitis. Sixty-three of these were from 2 schools in urban areas of the Dominican capital Santo Domingo (53%) and 55 were from rural schools on the border with Haiti (47%). The study included 84 boys (71. 18%) and 34 girls (28. 81%). The urban sample comprised mainly boys (84. 12%). The most represented age ranges were 6 to 8 years (47. 45%), 3 to 5 years (24. 59%), and 9 to 11 years (16. 94%). Microsporum audouinii (39. 68%), Trichophyton tonsurans (23. 80%), Microsporum canis (19. 04%), and Trichophyton violaceum (1. 58%) were isolated from children in urban areas, whereas T. tonsurans (87%) and Trichophyton mentagrophytes (2%) were isolated from those in rural areas. Overall, T. tonsurans (61. 16%), M. audouinii (24. 27%), and M canis (11. 65%) were the most frequently isolated causative organisms, whereas T. violaceum and T. mentagrophytes were rarely reported. In urban areas of the Dominican Republic, tinea capitis was found mainly in boys, but in rural areas it was evenly distributed among boys and girls. The emergence of M. audouinii and an increase in T. tonsurans were found while M. canis continued to be present at lower frequencies. On the rural border with Haiti, there was a significant predominance of T. tonsurans.

    This study examined the effect of job-related health insurance on employment transitions (labor force exits, reductions in hours, and job changes) of older working cancer survivors. Using multivariate models, we compared longitudinal data for the period 1997–2002 from the Penn State Cancer Survivor Study to similar data for workers with no cancer history in the Health and Retirement Study, who were also ages 55 to 64 at follow up. The interaction of cancer survivorship with health insurance at diagnosis was negative and significant in predicting labor force exits, job changes, and transitions to part-time employment for both genders. The differential effect of job-related health insurance on the labor market dynamics of cancer survivors represents an additional component of the economic and psychosocial burden of cancer on survivors.

  5. Stock market speculation: Spontaneous symmetry breaking of economic valuation

    2000-09-01

    Firm foundation theory estimates a security's firm fundamental value based on four determinants: expected growth rate, expected dividend payout, the market interest rate and the degree of risk. In contrast, other views of decision-making in the stock market, using alternatives such as human psychology and behavior, bounded rationality, agent-based modeling and evolutionary game theory, expound that speculative and crowd behavior of investors may play a major role in shaping market prices. Here, we propose that the two views refer to two classes of companies connected through a "phase transition". Our theory is based on (1) the identification of the fundamental parity symmetry of prices (p→-p), which results from the relative direction of payment flux compared to commodity flux and (2) the observation that a company's risk-adjusted growth rate discounted by the market interest rate behaves as a control parameter for the observable price. We find a critical value of this control parameter at which a spontaneous symmetry-breaking of prices occurs, leading to a spontaneous valuation in absence of earnings, similarly to the emergence of a spontaneous magnetization in Ising models in absence of a magnetic field. The low growth rate phase is described by the firm foundation theory while the large growth rate phase is the regime of speculation and crowd behavior. In practice, while large "finite-time horizon" effects round off the predicted singularities, our symmetry-breaking speculation theory accounts for the apparent over-pricing and the high volatility of fast growing companies on the stock markets.

    Depressive disorders and symptoms are common among middle-aged women. The effects of hormones on depression remain unclear. This review aims to clarify the nature of depressive disorders during the menopause transition as well as their links with climacteric syndrome, sexuality, cardiovascular risk and cognitive function. The recent literature on depressive disorders and menopause is reviewed. Women are more vulnerable than men to depressive disorders. Endocrine influences have been postulated but differences in, for example, coping style and response to stress may also contribute to the gender difference in the prevalence of depressive disorders. Gender differences in socialization may lead to higher rates of depression in women. There are data top suggest that menopause and depression are associated, although there is not a common clear causative factor. Women with climacteric symptoms (hot flushes, night sweats, vaginal dryness and dyspareunia) are more likely to report anxiety and/or depressive symptoms. Bothersome vasomotor symptoms could be associated with sleep disturbances, which in turn can increase reports of anxiety and depressive symptoms. Biopsychosocial and partner factors have a significant influence on middle-aged women's sexuality and depressive disorders, and most antidepressants can have a negative effect on sexual response. Lastly, studies have consistently shown that women with high levels of depressive symptoms are at greater cardiovascular risk and have poorer cognitive function than non-depressed women. At present, a direct relationship between psychiatric symptoms and hormonal changes such as estrogen decrease has not been clearly found. Stress, educational level, ethnicity, socioeconomic factors and partner status may influence the prevalence and clinical course of both menopause symptoms and depressive disorders. Since in many cases depression is a lifelong condition, and is associated with severe comorbid conditions, further studies are

  9. Systems for 42 V mass-market automobiles

    Keim, Thomas A.

    With the introduction of the Toyota Crown Royal Saloon in August, 2001, 42 V automotive electrical systems made the transition from a technology for the future to present-day production. Nevertheless, there is widespread malaise in the 42 V technical community, stemming from a slower than expected introduction to the marketplace. This paper discusses some of the reasons for the slow adoption of this technology, and indicates a possible way forward. This paper looks beyond the initial uses of 42 V in limited-volume, high-end cars and light trucks, and discusses the prospects for 42 V in mass-market vehicles, given what is presently known about the technology. It is concluded that a case can be made for 42 V, even at some increment in cost. The motivation is improved fuel economy. The cost targets necessary for this benefit to be achieved are discussed, and new components being widely discussed as part of future electrical systems are evaluated for mass-market applications. New developments with higher potential are suggested.

    Gow, David W; Caplan, David N

    2012-01-01

    Granger causation analysis of high spatiotemporal resolution reconstructions of brain activation offers a new window on the dynamic interactions between brain areas that support language processing. Premised on the observation that causes both precede and uniquely predict their effects, this approach provides an intuitive, model-free means of identifying directed causal interactions in the brain. It requires the analysis of all non-redundant potentially interacting signals, and has shown that even "early" processes such as speech perception involve interactions of many areas in a strikingly large network that extends well beyond traditional left hemisphere perisylvian cortex that play out over hundreds of milliseconds. In this paper we describe this technique and review several general findings that reframe the way we think about language processing and brain function in general. These include the extent and complexity of language processing networks, the central role of interactive processing dynamics, the role of processing hubs where the input from many distinct brain regions are integrated, and the degree to which task requirements and stimulus properties influence processing dynamics and inform our understanding of "language-specific" localized processes.

    This research is motivated by the difference of market hygiene condition, where the market hygiene level is influenced by the environment around the market. In general, markets located near densely populated housing tend to be overlooked, while markets near elite housing tend to be clean. This condition is also influenced by marketers' awareness of market hygiene. If the market is near the elite neighbourhood, the level of awareness of sellers on cleanliness will be high. If the market is located in a densely populated area, sellers generally do not pay attention to cleanliness. The purpose of this research is to know the sellers's awareness of environmental cleanliness of Market Bulak, Klender Market and Rawamangun Market. Respondents in this study are sellers and buyers who make transactions in these 3 markets. This type of research is descriptive analysis with the method of observation and interview to 10 sellers in each market. Seller hygiene awareness are poor.

On this basis, this paper analyzes the business of electricity selling company, from the aspects of the transition of business ideas, improving the energy efficiency level, providing integrated energy solutions and innovating business management mode; and then, the service strategies of electricity selling companies are put forward.

  13. On the dynamic dependence and asymmetric co-movement between the US and Central and Eastern European transition markets

    2016-10-01

    In this paper, we attempt to evaluate the time-varying and asymmetric co-movement of CEE equity markets with the US stock markets around the subprime crisis and the resulting global financial crisis. The econometric approach adopted is based on recent development of time-varying copulas. For that, we propose a new class of time-varying copulas that allows for long memory behavior in both marginal and joint distributions. Our empirical approach relies on the flexibility and usefulness of bivariate copulas that allow to model not only the dynamic co-movement through time but also to account for any extreme interaction, nonlinearity and asymmetry in the co-movement patterns. The time-varying dependence structure can be also modeled conditionally on the economic policy uncertainty index of the crisis country. Empirical results show strong evidence of co-movement between the US and CEE equity markets and find that the co-movement exhibits large time-variations and asymmetry in the tails of the return distributions.

    2014-01-01

    In response to rising demands and treatment costs, and the need to achieve better value for money in the face of tight fiscal constraints, both the National Health Service and the public drug reimbursement system are undergoing important reforms. Concurrently, the pharmaceutical sector itself is also alleged to be experiencing significant changes, perhaps most notably, a decline of the blockbuster model of drug development and a growing focus on niche market products. As pharmaceutical development strategies evolve and the resulting drug products become more complex, regulatory and policy responses must be able to evolve along with them. We explore how in numerous jurisdictions, including the UK, proposals for 'adaptive licensing' on the regulatory side and 'performance-based risk sharing agreements' on the funding side are shifting the focus of drug regulation and reimbursement towards more incremental access to new therapies and more post-market evidence generation. However, serious questions remain about how such reforms can be successfully implemented and whether they can balance demands for earlier access to promising new therapies with the need for robust evidence on safety, efficacy, and cost-effectiveness. © The Author 2014.

    PubMed

    Cooper, P D; King, K K

    1985-01-01

    Survey data were used to evaluate the role of marketing in the nonprofit arena of health promotion. Questionnaires utilizing a Likert type scale were sent to 106 marketers and 247 health educators soliciting their opinions about health care marketing. Both groups agreed that marketing was appropriate for both profit and non-profit organizations, but were not in total agreement on specific aspects of the marketing process. Marketers were adamant that marketing is not confined to promotional, advertising and communication functions, while health educators were neutral. Marketers were strong in their disagreement that marketing is selling; health educators were still neutral but in slight disagreement. Marketers did not believe that marketing uses gimmickry heavily, while health educators agreed that it does use gimmickry. A significant finding from the survey is that the major ethical issue for health educators is their view that marketing manipulates society. Both community and school health educators agreed that using marketing techniques is a step forward manipulation of a society, while the group of marketers disagreed.

    This paper studies the labour market returns to physical attractiveness using data from three transition countries of the Caucasus: Armenia, Azerbaijan and Georgia. I estimate a large positive effect of attractive looks on males' probability of employment. Results from the most comprehensive model suggest a marginal effect of 11.1 percentage points. Using a partial identification approach, I show that this relationship is likely to be causal. After accounting for covariates, particularly measures of human capital, there is no evidence for a statistically significant link between females' attractiveness and employment.

  20. Where Are the Babies? Labor Market Conditions and Fertility in Europe

    Cross-country differences in both the age at first birth and fertility are substantial in Europe. This paper uses distinct fluctuations in unemployment rates across European countries during the 1980s and the 1990s combined with broad differences in their labor market arrangements to analyze the associations between fertility timing and the changing economic environment with close to 50,000 women from thirteen European countries. First, it employs time varying measures of aggregate market conditions in each woman s country as covariates and second, it adds micro-measures of each woman s labor market history to the models. High and persistent unemployment in a country is associated with delays in childbearing (and second births). The association is robust to diverse measures of unemployment and to controls for family-friendly policies. Besides moderate unemployment, a large public employment sector (which provides security and benefits) is coupled with faster transitions to all births. Women with temporary contracts, mostly in Southern Europe, are the least likely to give birth to a second child. PMID:23580794

  1. Marketing is everything.

    PubMed

    McKenna, R

    1991-01-01

    Technology is creating customer choice, and choice is altering the marketplace. Gone are the days of the marketer as salesperson. Gone as well is marketing that tries to trick the customer into buying whatever the company makes. There is a new paradigm for marketing, a model that depends on the marketer's knowledge, experience, and ability to integrate the customer and the company. Six principles are at the heart of the new marketing. The first, "Marketing is everything and everything is marketing," suggests that marketing is like quality. It is not a function but an all-pervasive way of doing business. The second, "The goal of marketing is to own the market, not just to sell the product," is a remedy for companies that adopt a limiting "market-share mentality." When you own a market, you lead the market. The third principle says that "marketing evolves as technology evolves." Programmable technology means that companies can promise customers "any thing, any way, any time." Now marketing is evolving to deliver on that promise. The fourth principle, "Marketing moves from monologue to dialogue," argues that advertising is obsolete. Talking at customers is no longer useful. The new marketing requires a feedback loop--a dialogue between company and customer. The fifth principle says that "marketing a product is marketing a service is marketing a product." The line between the categories is fast eroding: the best manufacturing companies provide great service, the best service companies think of themselves as offering high-quality products. The sixth principle, "Technology markets technology," points out the inevitable marriage of marketing and technology and predicts the emergence of marketing workstations, a marketing counterpart to engineers' CAD/CAM systems.

    Identifying new potential treatment options for medical conditions that cause human disease burden is a central task of biomedical research. Since all candidate drugs cannot be tested with animal and clinical trials, in vitro approaches are first attempted to identify promising candidates. Likewise, identifying different causal relations between biomedical entities is also critical to understand biomedical processes. Generally, natural language processing (NLP) and machine learning are used to predict specific relations between any given pair of entities using the distant supervision approach. To build high accuracy supervised predictive models to predict previously unknown treatment and causative relations between biomedical entities based only on semantic graph pattern features extracted from biomedical knowledge graphs. We used 7000 treats and 2918 causes hand-curated relations from the UMLS Metathesaurus to train and test our models. Our graph pattern features are extracted from simple paths connecting biomedical entities in the SemMedDB graph (based on the well-known SemMedDB database made available by the U.S. National Library of Medicine). Using these graph patterns connecting biomedical entities as features of logistic regression and decision tree models, we computed mean performance measures (precision, recall, F-score) over 100 distinct 80-20% train-test splits of the datasets. For all experiments, we used a positive:negative class imbalance of 1:10 in the test set to model relatively more realistic scenarios. Our models predict treats and causes relations with high F-scores of 99% and 90% respectively. Logistic regression model coefficients also help us identify highly discriminative patterns that have an intuitive interpretation. We are also able to predict some new plausible relations based on false positives that our models scored highly based on our collaborations with two physician co-authors. Finally, our decision tree models are able to retrieve

    Weeks, John; Pugh, Jerry

    In 2011, the DOE issued Funding Opportunity DE-FOA-0000554 as a means of addressing two major task areas identified by the Grid Integration Tech Team (GITT) that would help transition Electric vehicles from a market driven by early adopters and environmental supporters to a market with mainstream volumes. Per DE-FOA-0000554, these tasks were: To reduce the cost of Electric Vehicle Supply Equipment (EVSE), thereby increasing the likelihood of the build out of EV charging infrastructure. The goal of increasing the number of EVSE available was to ease concerns over range anxiety, and promote the adoption of electric vehicles: To allow EVmore » loads to be managed via the smart grid, thereby maintaining power quality, reliability and affordability, while protecting installed distribution equipment. In December of that year, the DOE awarded one of the two contracts targeted toward commercial EVSE to Eaton, and in early 2012, we began in earnest the process of developing a Smart Grid Enable L2 EVSE for the Commercial Market (hereafter known as the DOE Charger). The design of the Smart Grid Enabled L2 EVSE was based primarily on the FOA requirements along with input from the Electric Transportation Infrastructure product line (hereafter ETI) marketing team who aided in development of the customer requirements.« less

  5. A study of a diffusive model of asset returns and an empirical analysis of financial markets

    NASA Astrophysics Data System (ADS)

    Alejandro Quinones, Angel Luis

    A diffusive model for market dynamics is studied and the predictions of the model are compared to real financial markets. The model has a non-constant diffusion coefficient which depends both on the asset value and the time. A general solution for the distribution of returns is obtained and shown to match the results of computer simulations for two simple cases, piecewise linear and quadratic diffusion. The effects of discreteness in the market dynamics on the model are also studied. For the quadratic diffusion case, a type of phase transition leading to fat tails is observed as the discrete distribution approaches the continuum limit. It is also found that the model captures some of the empirical stylized facts observed in real markets, including fat-tails and scaling behavior in the distribution of returns. An analysis of empirical data for the EUR/USD currency exchange rate and the S&P 500 index is performed. Both markets show time scaling behavior consistent with a value of 1/2 for the Hurst exponent. Finally, the results show that the distribution of returns for the two markets is well fitted by the model, and the corresponding empirical diffusion coefficients are determined.

  6. The roles of users in shaping transitions to new energy systems

    Schot, Johan; Kanger, Laur; Verbong, Geert

    2016-05-01

    Current government information policies and market-based instruments aimed at influencing the energy choices of consumers often ignore the fact that consumer behaviour is not fully reducible to individuals making rational conscious decisions all the time. The decisions of consumers are largely configured by shared routines embedded in socio-technical systems. To achieve a transition towards a decarbonized and energy-efficient system, an approach that goes beyond individual consumer choice and puts shared routines and system change at its centre is needed. Here, adopting a transitions perspective, we argue that consumers should be reconceptualized as users who are important stakeholders in the innovation process shaping new routines and enacting system change. We review the role of users in shifts to new decarbonized and energy-efficient systems and provide a typology of user roles.

  7. Trend Switching Processes in Financial Markets

    NASA Astrophysics Data System (ADS)

    Preis, Tobias; Stanley, H. Eugene

    For an intriguing variety of switching processes in nature, the underlying complex system abruptly changes at a specific point from one state to another in a highly discontinuous fashion. Financial market fluctuations are characterized by many abrupt switchings creating increasing trends ("bubble formation") and decreasing trends ("bubble collapse"), on time scales ranging from macroscopic bubbles persisting for hundreds of days to microscopic bubbles persisting only for very short time scales. Our analysis is based on a German DAX Future data base containing 13,991,275 transactions recorded with a time resolution of 10- 2 s. For a parallel analysis, we use a data base of all S&P500 stocks providing 2,592,531 daily closing prices. We ask whether these ubiquitous switching processes have quantifiable features independent of the time horizon studied. We find striking scale-free behavior of the volatility after each switching occurs. We interpret our findings as being consistent with time-dependent collective behavior of financial market participants. We test the possible universality of our result by performing a parallel analysis of fluctuations in transaction volume and time intervals between trades. We show that these financial market switching processes have features similar to those present in phase transitions. We find that the well-known catastrophic bubbles that occur on large time scales - such as the most recent financial crisis - are no outliers but in fact single dramatic representatives caused by the formation of upward and downward trends on time scales varying over nine orders of magnitude from the very large down to the very small.

    Many dynamical systems, including lakes, organisms, ocean circulation patterns, or financial markets, are now thought to have tipping points where critical transitions to a contrasting state can happen. Because critical transitions can occur unexpectedly and are difficult to manage, there is a need for methods that can be used to identify when a critical transition is approaching. Recent theory shows that we can identify the proximity of a system to a critical transition using a variety of so-called ‘early warning signals’, and successful empirical examples suggest a potential for practical applicability. However, while the range of proposed methods for predicting critical transitions is rapidly expanding, opinions on their practical use differ widely, and there is no comparative study that tests the limitations of the different methods to identify approaching critical transitions using time-series data. Here, we summarize a range of currently available early warning methods and apply them to two simulated time series that are typical of systems undergoing a critical transition. In addition to a methodological guide, our work offers a practical toolbox that may be used in a wide range of fields to help detect early warning signals of critical transitions in time series data.

    Famously, dog bites man is trivia whereas man bites dog is news. This illustrates not just a fact about the world but about language: to know who did what to whom, we must correctly identify the mapping between semantic role and syntactic position. These mappings are typically predictable, and previous work demonstrates that young children are sensitive to these patterns and so could use them in acquisition. However, there is only limited and mixed evidence that children do use this information to guide acquisition outside of the laboratory. We find that children understand emotion verbs which follow the canonical CAUSE-VERB-PATIENT pattern (Mary frightened/delighted John) earlier than those which do not (Mary feared/liked John), despite the latter's higher frequency, suggesting children's generalization of the mapping between causativity and transitivity is broad and active in acquisition.

    This paper explores a multi-model scenario ensemble to assess the impacts of idealized and non-idealized climate change stabilization policies on fossil fuel markets. Under idealized conditions climate policies significantly reduce coal use in the short- and long-term. Reductions in oil and gas use are much smaller, particularly until 2030, but revenues decrease much more because oil and gas prices are higher than coal prices. A first deviation from optimal transition pathways is delayed action that relaxes global emission targets until 2030 in accordance with the Copenhagen pledges. Fossil fuel markets revert back to the no-policy case: though coal use increasesmore » strongest, revenue gains are higher for oil and gas. To balance the carbon budget over the 21st century, the long-term reallocation of fossil fuels is significantly larger—twice and more—than the short-term distortion. This amplifying effect results from coal lock-in and inter-fuel substitution effects to balance the full-century carbon budget. The second deviation from the optimal transition pathway relaxes the global participation assumption. The result here is less clear-cut across models, as we find carbon leakage effects ranging from positive to negative because trade and substitution patterns of coal, oil, and gas differ across models. In summary, distortions of fossil fuel markets resulting from relaxed short-term global emission targets are more important and less uncertain than the issue of carbon leakage from early mover action.« less

  12. Encouraging the use of generic medicines: implications for transition economies.

    PubMed

    King, Derek R; Kanavos, Panos

    2002-08-01

    Generic drugs have a key role to play in the efficient allocation of financial resources for pharmaceutical medicines. Policies implemented in the countries with a high rate of generic drug use, such as Canada, Denmark, Germany, the Netherlands, the United Kingdom, and the United States, are reviewed, with consideration of the market structures that facilitate strong competition. Savings in these countries are realized through increases in the volume of generic drugs used and the frequently significant differences in the price between generic medicines and branded originator medicines. Their policy tools include the mix of supply-side measures and demand-side measures that are relevant for generic promotion and higher generic use. On the supply-side, key policy measures include generic drug marketing regulation that facilitates market entry soon after patent expiration, reference pricing, the pricing of branded originator products, and the degree of price competition in pharmaceutical markets. On the demand-side, measures typically encompass influencing prescribing and dispensing patterns as well as introducing a co-payment structure for consumers/patients that takes into consideration the difference in cost between branded and generic medicines. Quality of generic medicines is a pre-condition for all other measures discussed to take effect. The paper concludes by offering a list of policy options for decision-makers in Central and Eastern European economies in transition.

    Information theory can help to recognize magnetic phase transitions, what can be seen as a way to recognize different regimes. This is achieved by means of zippers specifically designed to compact data in a meaningful way at is the case for compressor wlzip. In the present contribution we first apply wlzip to the Chilean stock market interpreting the compression rates for the files storing the minute variation of the IPSA indicator. Agitated days yield poor compression rates while calm days yield high compressibility. We then correlate this behavior to the value of the five retirement funds related to the Chilean economy. It is found that the covariance between the profitability of the retirement funds and the compressibility of the IPSA values of previous day is high for those funds investing in risky stocks. Surprisingly, there seems to be no great difference among the three riskier funds contrary to what could be expected from the limitations on the portfolio composition established by the laws that regulate this market.

    There is not enough marketing of dentistry; but there certainly is too much selling of poor quality service that is being passed off as dentistry. The marketing concept makes the patient and the patients' needs the ultimate criteria of marketing efforts. Myths and good practices for effective marketing that will promote oral health are described under the traditional four "Ps" categories of "product" (best dental care), "place" (availability), "promotion" (advertising and other forms of making patients aware of available services and how to use them), and "price" (the total cost to patients of receiving care).

  20. From General Game Descriptions to a Market Specification Language for General Trading Agents

    NASA Astrophysics Data System (ADS)

    Thielscher, Michael; Zhang, Dongmo

    The idea behind General Game Playing is to build systems that, instead of being programmed for one specific task, are intelligent and flexible enough to negotiate an unknown environment solely on the basis of the rules which govern it. In this paper, we argue that this principle has the great potential to bring to a new level artificially intelligent systems in other application areas as well. Our specific interest lies in General Trading Agents, which are able to understand the rules of unknown markets and then to actively participate in them without human intervention. To this end, we extend the general Game Description Language into a language that allows to formally describe arbitrary markets in such a way that these specifications can be automatically processed by a computer. We present both syntax and a transition-based semantics for this Market Specification Language and illustrate its expressive power by presenting axiomatizations of several well-known auction types.

    Youth smoking is a global public health concern. Health educators are increasingly using Internet-based technologies, but the effectiveness of Internet viral marketing in promoting health remains uncertain. This prospective pilot study assessed the efficacy of an online game-based viral marketing campaign in promoting a smoke-free attitude among Chinese adolescents. One hundred and twenty-one Hong Kong Chinese adolescents aged 10 to 24 were invited to participate in an online multiple-choice quiz game competition designed to deliver tobacco-related health information. Participants were encouraged to refer others to join. A zero-inflated negative binomial model was used to explore the factors contributing to the referral process. Latent transition analysis utilising a pre- and post-game survey was used to detect attitudinal changes toward smoking. The number of participants increased almost eightfold from 121 to 928 (34.6% current or ex-smokers) during the 22-day campaign. Participants exhibited significant attitudinal change, with 73% holding negative attitudes toward smoking after the campaign compared to 57% before it. The transition probabilities from positive to negative and neutral to negative attitudes were 0.52 and 0.48, respectively. It was also found that attempting every 20 quiz questions was associated with lower perceived smoking decision in future (OR = 0.95, p-value <0.01). Our online game-based viral marketing programme was effective in reaching a large number of smoking and non-smoking participants and changing their attitudes toward smoking. It constitutes a promising practical and cost-effective model for engaging young smokers and promulgating smoking-related health information among Chinese adolescents.

    In an electric power day-ahead market, market prices are not always cleared at marginal cost caused by the strategic bidding of generators. This paper presents the results of day-ahead market simulation that analyzes profits depending upon bidding strategies in an electric power day-ahead market. It is clarified that MCP (Market Clearing Price) is easily managed by only one player and does not easily decline after it has gone up once. Moreover the mutual interference among day-ahead markets, future markets, increase of generators, etc. are also discussed.

  4. The Mongolia experience: transitioning within transition.

    2009-12-01

    Although Mongolia has a long and distinguished history, as a new and emerging democracy it is experiencing the pains of transition-one that is moving the country from its pastoral and nomadic past into the 21st century. Confounded by its previous dependence on socialist Soviet Russia, the concept of a market economy seems opportunistic for some, while for those living within the traditional lifestyle of the herdsman in the countryside it is confusing and threatening to family structure and values. Adolescents and young adults are caught at the interface-not only of their own development, but by the disparities between tradition and Western values, new technology, and freedoms granted by the emerging democracy, and by the civic practice of democracy itself. Conceptually the new belongs to the young, and yet limited health and educational resources are available to modulate and focus both threats and opportunities. Using the analogy of the spirit banner of the warrior, it is the young as the warriors of the 21st century who have the energy and investment in the future that will be needed to shepherd this change. Both personal and public health, within the context of development, the psychobiological model, and the political and social ecology will be strong determinants of success. It is a parallel investment in both youth and the ideals they represent that will ensure success for the new Mongolia.

    The recent discovery of bovine haplotypes with negative effects on fertility in the Brown Swiss, Holstein, and Jersey breeds has allowed producers to identify carrier animals using commercial single nucleotide polymorphism (SNP) genotyping assays. This study was devised to identify the causative mutations underlying defective bovine embryo development contained within three of these haplotypes (Brown Swiss haplotype 1 and Holstein haplotypes 2 and 3) by combining exome capture with next generation sequencing. Of the 68,476,640 sequence variations (SV) identified, only 1,311 genome-wide SNP were concordant with the haplotype status of 21 sequenced carriers. Validation genotyping of 36 candidate SNP identified only 1 variant that was concordant to Holstein haplotype 3 (HH3), while no variants located within the refined intervals for HH2 or BH1 were concordant. The variant strictly associated with HH3 is a non-synonymous SNP (T/C) within exon 24 of the Structural Maintenance of Chromosomes 2 (SMC2) on Chromosome 8 at position 95,410,507 (UMD3.1). This polymorphism changes amino acid 1135 from phenylalanine to serine and causes a non-neutral, non-tolerated, and evolutionarily unlikely substitution within the NTPase domain of the encoded protein. Because only exome capture sequencing was used, we could not rule out the possibility that the true causative mutation for HH3 might lie in a non-exonic genomic location. Given the essential role of SMC2 in DNA repair, chromosome condensation and segregation during cell division, our findings strongly support the non-synonymous SNP (T/C) in SMC2 as the likely causative mutation. The absence of concordant variations for HH2 or BH1 suggests either the underlying causative mutations lie within a non-exomic region or in exome regions not covered by the capture array.

  7. Democratizing Energy Access in a Marketized World: The Cases of Costa Rica and Nicaragua

    NASA Astrophysics Data System (ADS)

    Colbert, M'Lisa Lee

    This thesis explores the experiences, motivations and the imaginary of people who seek to democratize access to energy. Through a survey of the energy democracy movement in Europe and North America and a case study of two participatory and democratically oriented electricity providers in Central America, this thesis examines the differences and similarities between democratizing energy in the Global North and Global South in the context of marketization and the global push to transition to renewable energy. The forces of an expanding global energy economy are increasingly influencing the way that we can access and consume energy in our lives. Local interactions cannot be understood by an isolated analysis without considering the larger structural conditions that implicate them. Today, we are witnessing a global push to transition our energy resources from fossil fuels to renewables due to the emergency of climate change. For the most part, this transition preoccupies itself with changing the technological instruments that source us the energy. Yet few changes are targeting transition from growth focused market-based economic models. Energy Democracy is one new imaginary that people are rallying around to help realize alternatives to drive more equitable and sustainable post-carbon futures. This thesis finds that there are unfounded normative assumptions being made about groups organizing around energy democracy that is causing scatter in the movement. There is an aggressive strand of energy democracy that readily accepts for-profit schemes and risks turning energy democracy into just another space for capital accumulation in the energy sector. This thesis presents two important suggestions for reconciling these problems. Firstly, to look beyond moving the term itself and prioritize connecting on the basis of the underlying principles that define the term. This will ultimately create more meaningful solidarity in the future, and a more grounded and unified movement

  8. Isolation, experimental transmission, and characterization of causative agent of Potomac horse fever.

    Potomac horse fever, a disease characterized by fever, anorexia, leukopenia, and occasional diarrhea, is fatal in approximately 30 percent of affected animals. The seasonal occurrence of the disease (June to October) and evidence of antibodies to the rickettsia Ehrlichia sennetsu in the serum of convalescing horses suggested that a related rickettsia might be the causative agent. Such an agent was isolated in cultured blood monocytes from an experimentally infected pony. This intracytoplasmic organism was adapted to growth in primary cultures of canine blood monocytes. A healthy pony inoculated with these infected monocytes also developed the disease. The organism was reisolated from this animal which, at autopsy, had pathological manifestations typical of Potomac horse fever. Cross serologic reactions between the newly isolated agent and antisera to 15 rickettsiae revealed that it is related to certain members of the genus Ehrlichia, particularly to Ehrlichia sennetsu. Since the disease occurs in other parts of the United States as well as in the vicinity of the Potomac River, and since it has also been reported in Europe, the name equine monocytic ehrlichiosis is proposed as being more descriptive.

    The fungistatic and fungicidal activities of sertaconazole against dermatophytes were evaluated by testing 150 clinical isolates of causative agents of tinea pedis, Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum. The overall geometric means for fungistatic and fungicidal activities of sertaconazole against these isolates were 0.26 and 2.26 μg/ml, respectively, although values were higher for T. mentagrophytes than for the others. This is the first comprehensive demonstration of the fungicidal activity of sertaconazole against dermatophytes. PMID:21746955

    This article looks at a prescribed academic framework for various criteria that serve as a checklist for marketing performance that can be applied to hospital marketing organizations. These guidelines are drawn from some of Dr. Noel Capon of Columbia University's book Marketing Management in the 21st Century and applied to actual practices of hospital marketing organizations. In many ways this checklist can act as a "marketing" balanced scorecard to verify performance effectiveness and develop opportunities for innovation.

    2014-01-01

    In this paper we introduce methodology—causal directed acyclic graphs—that empirical researchers can use to identify causation, avoid bias, and interpret empirical results. This methodology has become popular in a number of disciplines, including statistics, biostatistics, epidemiology and computer science, but has yet to appear in the empirical legal literature. Accordingly we outline the rules and principles underlying this new methodology and then show how it can assist empirical researchers through both hypothetical and real-world examples found in the extant literature. While causal directed acyclic graphs are certainly not a panacea for all empirical problems, we show they have potential to make the most basic and fundamental tasks, such as selecting covariate controls, relatively easy and straightforward.

    This chapter outlines current marketing practice from a managerial perspective. The role of marketing within an organization is discussed in relation to efficiency and adaptation to changing environments. Fundamental terms and concepts are presented in an applied context. The implementation of marketing plans is organized around the four P's of marketing: product (or service), promotion (including advertising), place of delivery, and pricing. These are the tools with which marketers seek to better serve their clients and form the basis for competing with other organizations. Basic concepts of strategic relationship management are outlined. Lastly, alternate viewpoints on the role of advertising in healthcare markets are examined.

    Transitioning from twenty-five years of space communication system architecting, engineering and development to creating and marketing of commercial communication system hardware and software products is no simple task for small, high-tech system engineering companies whose major source of revenue has been the U.S. Government. Yet, many small businesses are faced with this onerous and perplexing task. The purpose of this talk/paper is to present one small business (LinCom) approach to taking advantage of the systems engineering expertise and knowledge captured in physical neural networks and simulation software by supporting numerous National Aeronautics and Space Administration (NASA) and the Department of Defense (DoD) projects, e.g., Space Shuttle, TDRSS, Space Station, DCSC, Milstar, etc. The innovative ingredients needed for a systems house to transition to a wireless communication system products house that supports personal communication services and networks (PCS and PCN) development in a global economy will be discussed. Efficient methods for using past government sponsored space system research and development to transition to VLSI communication chip set products will be presented along with notions of how synergy between government and industry can be maintained to benefit both parties.

    2017-01-01

    The epithelial-to-mesenchymal transition (EMT) process allows the trans-differentiation of a cell with epithelial features into a cell with mesenchymal characteristics. This process has been reported to be a key priming event for tumor development and therefore EMT activation is now considered an established trait of malignancy. The transcriptional and epigenetic reprogramming that governs EMT has been extensively characterized and reviewed in the last decade. However, increasing evidence demonstrates a correlation between metabolic reprogramming and EMT execution. The aim of the current review is to gather the recent findings that illustrate this correlation to help deciphering whether metabolic changes are causative or just a bystander effect of EMT activation. The review is divided accordingly to the catabolic and anabolic pathways that characterize carbohydrate, aminoacid, and lipid metabolism. Moreover, at the end of each part, we have discussed a series of potential metabolic targets involved in EMT promotion and execution for which drugs are either available or that could be further investigated for therapeutic intervention.
